RE: [GD-Windows] Release build confusion

[Chris R. <c....@gm...>]

That actually worked out pretty well.

I still believe (although I am not sure) that the debugger injects it's
memory handlers into the running application at the point it attaches
itself to the process.

I let my application run for a while and attached the debugger later on
- and I easily could pinpoint the offending line of code which caused
this mayhem after a few retries and a few minutes of heavy thinking. We
actually had two memory related issues - one uninitialized pointer, and
as an indirect consequence of that, we took the pointer of an object on
the stack and used it after it was destroyed long ago.

Thanks for all the insights (especially the _heapfill()&co functions)!

regards, 
Chris Raine
