The failure is non-deterministic.

** TODO (issue #762) malloc drheapstat leak count off

I've started seeing this w/ both VS2008 and VS2010 on Win7 machines

for me, it's missing this leak:
: LEAK 16 direct bytes + 48 indirect bytes
malloc.c:251

based on Qin's prior analysis and what I'm seeing this is almost certainly issue #292 (RtlpHeapFailureInfo) and drheapstat just doesn't have online syms.

I'm going to add online syms but just for this (too much work to change rest of drheapstat: that's covered by issue #828 and issue #926 )
