My previous post explained that for 32-bit process, 32-bit tool should be used, or most tools got confused. Visual Studio able to handle standard PDB files but got confused on PDB files that was custom generated. Normally I would recommend using 32-bit tool and forget about this problem. But in some cases, crash could be so rare, that it worth investigating how to get anything useful from such “bad” dump. And I will show, how to do it.

Firstly, load 32-bit WinDbg and execute following commands:
.load wow64exts.dll
!sw
!r

This will load standard wow64exts WinDbg extension, switch to 32-bit mode, even dump is 64 bit and displays 32-bit context record. From context record
