On the code from issue #360 and Win7 (not XP32), I see the following memory leak:

Error #1: LEAK 24 direct bytes 0x004fcdb8-0x004fcdd0 + 0 indirect bytes
0x77459fcb <ntdll.dll+0x39fcb> ntdll.dll!RtlAllocateActivationContextStack

Derek, have you seen this leak before?

I'll re-run with symbols

Running
_NT_SYMBOL_PATH=C:\src\symbols ./bin/drmemory.exe -batch -- threads_win.exe
with "wntdll.pdb" in C:\src\symbols haven't changed a thing.

xref issue #249 : RtlAllocateActivationContextStack leak auto-suppressed when
called from createthread but was not analyzed enough, should be revisited

xref issue #352 : RtlCreateActivationContext allocated by csrss
