Hi fellow developers,I have bound the _melange_ memory allocation functions to a custom memory manager initialized only after the program have reached WinMain().
In Release mode only, it seems that _melange_ use some kinf of CRT instructions to init the inner structure _melange_::InitStrings, whose constructor calls _melange_::InitStrings::InitStrings().
It leads to two calls to _melange_::MemAlloc(VLONG), each one trying to allocate 131072 bytes before I even get the chance to execute a line of my code.
I've found a workaround to prevent my allocator for crashing but it's not efficient nor elegant.

Hi,
we've changed the InitStrings() to use only static memory so there should be no more memory allocation before your memory management is initialized.
Please check with the next upcoming Melange version (I guess it will be released around the second week of january 2013).Thank you for pointing out this issue!
Cheers,
Jens -

Whoo that was fast, good work ! I'll use this new build in no time !
By the way, the Developer support page where the Melange library can be downloaded still states that the current build is the #68456 one
