std::bad_alloc with mingw under windows 7

[Andreas]

Hi all,

currently i can't debug my game with (mingw) gdb under windows7 because i always get the following error:

 
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc

The strange thing is, this is only when debugging the game with gdb. When i run the game normally, everything works.

Strangely it worked before. I suspect some windows update and already re-compiled irrlicht, but it didn't help.

Since i'm completely out of ideas, any help, hint or comment how to solve this would be highly appreciated!

Best regads

Do you get that right from the start? Or can you start debugging and this happens after a while? When things are that crazy I usually start to comment out code in my application until only the crash is left (divide and conquer debugging technique). Which can take a while in larger applications (took me once 3 days until I had reduced it to a test-case for gdb which those guys fixed then...).

I can start debugging and even do the first move in the game, but then the following code from irrAllocator.h throws the exception:

Code: Select all

 
virtual void* internal_new(size_t cnt)
    {
        return operator new(cnt);
    }
 

The code is called from my game:

Code: Select all

 
map<EPLAYER_ID, array<SUnit> >::Node *node = units.find(playerId);
    if (node) {
        array<SUnit> units = node->getValue(); // <<<----- causing the problem
        ...
   }
 

But i can't image what the problem could be, because as i said, during normal execution the program runs fine.

I also can't tell from that code alone. Well, divide and conquer really helps in such cases - you remove everything until you only have the crashing code left. It often clears things up. Or at least makes good test-cases which you can pass around then.

OK, i will try to gather more information about the problem. Maybe i can isolate it, as you said, and find a solution.

Thanks for the very fast help!
