Windows – Loading a 64-bit crash .dmp for a 32-bit application

September 20, 2010

If a crash dump shows WOW64 CPU emulation in all threads (e.g.  wow64cpu.dll!CpuSysCallStub() …) then a 64-bit dump has been generated for a 32-bit process.

To view the stack the wow 64-bit extensions need to be loaded first into Windbg:

In Windbg:

0:000> .load wow64exts
0:000> .effmach x86
Effective machine: x86 compatible (x86)
0:000:x86> !analyze -v
