No words like local or global catch.

"there is no way to catch exceptions from the initialization of global variables (section 14.7)"

This will catch every exception, except those thrown by construction and destruction of global variables. There is no way of catching exceptions thrown during initialization of global variables. The only way of gaining control in case of throw from an initializer of a nonlocal static object is set_unexpected ($14.6.2). This is another reason to avoid global variable whenever possible.

int main()
try {
}
catch(std::range_error) {
}
catch(std::bad_alloc) {
}
catch(...) {
}

Any comments after reading this and reviewing my code sample above?

I do not think I am always correct

Yes, the reported original words confirm my observation: if a constructor throws and then catches itself, outside of the construction process you see nothing,

hence Bjarne obviously refers to exceptions thrown by global object constructors AND not catched inside the constructors themselves.

We can do anything as we like to do in exception handler, like write log.

But my original understanding is, there is no way to catch exceptions from constructor of global variables -- not the limitatino of catching exceptions in main.

you haven't control to internal details of the global object you're instancing hence
