The idea is bad. Don't allow any memory leaks at all. Such questions as this one are useless.
Use the leak detection software.

No that will not fix it. The problem is that your program is consuming memory but not releasing it. You need to fix the bugs (or the design) in your code.

Your program is guilty consuming all memory.
2 Solutions: don't use it or do corrections.

Preventing memory leaks in Delphi is extremely easy, much easier than with most other systems (those without garbage collection, of course). There are products which do all detection for you, without any of your help. It takes just one call to activate them.

I used to use MemChk, it worked flawlessly: MemCheck home page[^].

Presently I use Free Pascal, and highly recommend it, even if you use Delphi; Free Pascal is deeply cross-platform, with very interesting UI abstraction layer, which helps you to develop UI for very many platforms at the same time. It invokes similar memory leak finder automatically, just by checking one of the project options. Most likely, you can fetch its source code and use it for Deplhi as well. It's called Heaptrc. It also works flawlessly. Please see:
heaptrc[^],
leakview[^].

The second link shows advanced usage; in most cases you need nothing of it. Usually, you don't need anything like that.

Solution 1

Avoiding memory leaks is one of the main duties of the software developer. As correctly pointed out by Sergey, your code should correctly handle memory allocation/deallocation.
Hence the right approach here is revising the code in order to make it perform the necessary deallocations.

You are right, but I voted 4 this time, because the possibilities to track memory leaks are much more advanced with Delphi and Free Pascal; the leaks are found in no time and fixed without any effort. Please see Solution 2.

No Delphi development can be called literate if such tools are not used.
