--- Comment #27 from Anastasius Focht <focht at gmx.net> ---
Hello folks,

this might be a multi-threading application bug that just works in some cases
by pure luck.

Although you can limit the 'cruncher' threads ('--threads=1') it will still
fail when '--algorithm=NTLM1' is supplied via command line.
All 'secondary' cruncher threads work the same way.
Each thread gets its own instance data located in .data section.

The outcome is that an invalid memory block is passed to HeapReAlloc() which
fails the heap manager validation (expected).

Comment #24 says it doesn't work on Windows 7 with following command line which
indicates this might be indeed an application bug.

MDCrack-sse.exe --threads=1 --charset=TEStes --algorithm=NTLM1
