When the VC6 C runtime on XP can't serve an allocation request within an existing heap segment, it reserves a new segment. The size of these new segments increase by factors of 2 (until there are not large enough free areas to do that, at which point it falls down to smaller segments.)
In any case, is there any way to control this behavior on XP with the VC6 runtime? For example, doubling up to a point, but capping at 64MB segments.
If there is no way on XP but there is on 7, that would be good to know too. Or if there is no way on VC6 but there is on VC8 or up would be interesting.
