Crash Dump Analysis

It looks like Microsoft has introduced the “Blame Module” concept in addition to the old Windows “Crashed Module” terminology in Microsoft Error Reporting for Mac OS X. I noticed that yesterday when the freshly installed out of the box Microsoft Word 2008 for Mac crashed on my new MacBook Air. Digging into the report I noticed this:

Microsoft Error Reporting log version: 2.0

Error Signature:
Exception: EXC_BAD_ACCESS
Date/Time: 2008-05-16 01:15:21 +0100
Application Name: Microsoft Word
Application Bundle ID: com.microsoft.Word
Application Signature: MSWD
Application Version: 12.0.0.071130
Crashed Module Name: HIToolbox
Crashed Module Version: unknown
Crashed Module Offset: 0x0006118f
Blame Module Name: HIToolbox
Blame Module Version: unknown
Blame Module Offset: 0×0006118f
Application LCID: 1033
Extra app info: Reg=en Loc=0×0409

In the report itself it is nice to see stack traces and thread context in familiar Intel syntax:

I installed Microsoft Office 2008 SP1 and hope it resolves the issue.

As a happy owner of an Apple MacBook Air Laptop I’m introducing the new blog category where I’m going to dig into crash dump analysis on Mac OS X and FreeBSD whenever an occasion happens.

In order to seamlessly analyze Windows crash dumps and use WinDbg I also bought VMware Fusion

and Microsoft Office 2008 for Mac to write about my experience:
