I don't think that's the problem here.

The "Two many heap sections" error in large part reflects a Windows-specific bug that was recently fixed in the GC source.
The large size difference indicates another problem. Calling GC_dump() from a debugger, or setting the GC_DUMP_REGULARLY environment variable (and possibly the GC_PRINT_STATS variable) might give you some idea what's in the heap and what's causing it.
