If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?

How long to wait until the Wagner/Putin circus is revealed as an elaborately staged deception designed to hide some military nightmare in the making, to flush out Putin opponents worthy of a free happy-hour novichok cocktail, or assisted out-a-window take off ? An agitprop appetizer for flagging nationalism ?

Hrmmm.
I have some code with suspected heap corruption. I've pored over it and can't find anything. However, the modifications I've made to the codebase in an attempt to run it down have actually yielded a copy that works reliably on several devices - devices that don't use a display with an "RGB interface" bus.
On any display with an RGB interface bus the device hangs as soon as it receives serial data and rebuilds the display with it. Complete hard freeze, requiring a reflash or hard reset.
I might be able to work around this by switching out my lcd_init.h with something like LovyanGFX to do my last mile display communication.
However, lcd_init.h has never caused me problems before. I suspect that even if switching it out "fixes" the problem, it will have more buried the bug than actually fixed it.
Now here's the thing with IoT, esp when you aren't using I/O bound multithreading or anything complicated to effect the following:
Every time I boot, if i call malloc and print that pointer I get back as a hex integer to the console, it will be the same value every single time (as long as the requested size is the same). If I create a thread on each core, and spit out "A" on one, and "B" on the other, I will get the same sequence of As and Bs every time, on every machine with the same chip.
That makes it very much unlike development on a PC. There aren't fiddly bits in the background making things non-deterministic.
The bottom line is, if I bury this bug well enough, for all practical purposes I have "fixed" it.
I hate this, but I know it to be true.
I don't want to use what I know to be true to move forward on this project. Burying the bug just doesn't sit right with me.
But it's an option. I wouldn't be the first to do it. Far from it.
Times like this call for a little Aesop Rock
Got an angel on my left shoulder, a devil on the polar

I peel back hearts and lodge greed physics in the chambers
Cauterize the wound and heads like
"Gimme gimme something major"
Road side prophetic, ascend well (well)
Enveloped in a mummy ribbon system
Blistering in a wishing well
BIG BANG!

2) When it's in the manual. Then it's a feature.

When a bug isn't really a bug?
When nobody complains about it.
|
|
|
|
|
Well, I suppose then this is potentially not a bug, since I've been the only one complaining so far.

But you're not "nobody".
I realize this is probably way beyond anything I've ever produced, but maybe my naive thinking can help. Take my line of questioning for whatever it's worth.
What does it take to reproduce the bug? Can you reproduce it consistently? Once you know how to reproduce it, can you come up with a way to end up with the desired results, but avoiding the path that causes the bug to surface? Can you comment out large chunks of code until the bug stops happening (assuming you know how to reproduce it consistently in the first place)? If so, can you then start uncommenting code, little-by-little until it comes up again? When that happens, comment it out once more and keep uncommenting the rest of it until everything's been restored except for the buggy part. Of course if things are chained in such a way that for function A to work, it needs the output of function B, and commenting things out as I'm suggesting might not be an option.
That's my idea anyway. I hate to go in blind, but sometimes if looking at code doesn't yield any results, no matter how long and hard you look at it, removing it and adding it back one bit at a time can be useful.

That's what I've been doing and why I know it's probably heap corruption.
Check this out, I thought I had isolated it to a section of code. But it wasn't that code. Because undoing a different section of code, that code starts working again. It's like pushing a bubble out of a waterbed. It just keeps moving around.
I've got it now where it functions as i said, on everything but RGB displays, where it completely hangs. I MIGHT be able to work around the hang, but without knowing what is causing this, even getting it to work, it still makes me uneasy.

Although that doesn't always happen it should not be a surprise.
When you change the execution flow you are always going to change the data space of the application. That applies to stack, heap, etc.
Those changes can cause an overwrite/underwrite to move in the data space. And thus the system exception will appear and disappear. Could be that it never fails after that or it could just move to a different failure point. Because it really does matter where the bad write goes.

It does. But if that bad write doesn't actually cause an issue, and the app can be tested to work under those conditions, with that particular firmware, is it worth releasing? not for anything mission critical - it's a tool to monitor your PC's temps and usage.
Sort of a philosophical question if anything.

Perhaps in your situation (as per your other point about deterministic threads.)
If you can be assured of the data flow then the error is going to be there but not be impacting anything.
When I worked in C/C++ I knew the data flow was not predictable. So I could not have left that in any of those systems.

I've decided not to release it. It's silly, but I decided to make my standard such that it must at least work on the device I embedded in my PC's chassis. Currently it does not. That's one of the problem devices.
I have some ideas on how to tip toe around this issue, but it involves static allocation. I've already tried lazy dynamic allocation, both with releasing/recreating and recycling. Neither method seems to work with my UIX library. I think if i make several static controls things might be okay, although I'd be hard pressed to understand why. Right now it's just a hunch.
