Crash Dump Analysis Patterns (Part 1d)

Thursday, September 8th, 2016

We do not write a special pattern for individual stowed exceptions (0xC000027B, an application-internal exception) because we consider them examples of Mixed Exceptions (for example, as Managed Code Exceptions enveloped by unmanaged code Software Exception, see stowed exception examples here). However, we introduce a variant of Multiple Exceptions analysis patterns for them because the default analysis WinDbg command (!analyze -v) only shows the first exception or error message stored in the array of stowed exception information structures. The following example shows 3 exceptions. When we load the dump we get this indication of the stowed exceptions:

This dump file has an exception of interest stored in it.
The stored exception information can be accessed via .ecxr.
(2784.2068): Unknown exception - code c000027b (first/second chance not available)
eax=059be538 ebx=00000000 ecx=00000000 edx=00000000 esi=059be898 edi=059be538

0:008> !error c000027b
Error code: (NTSTATUS) 0xc000027b (3221226107) - An application-internal exception has occurred.

We check Stored Exception:

0:008> .exr -1
ExceptionAddress: 66fc2408 (Windows_UI_Xaml!DirectUI::ErrorHelper::ProcessUnhandledError+0x00432e07)
ExceptionCode: c000027b
ExceptionFlags: 00000001
NumberParameters: 2
Parameter[0]: 08d9bfa8
Parameter[1]: 00000003

We see it has 3 stowed exceptions pointed to by array elements:

0:008> dp 08d9bfa8 L3
08d9bfa8 08d8e084 08d928a8 08d928d0

We check what kind of stowed information structures they point to:

0:008> dt -a3 08d9bfa8 _STOWED_EXCEPTION_INFORMATION_HEADER*

Since these are version 2 stowed information structures we use this command:

0:008> dt -a3 08d9bfa8 _STOWED_EXCEPTION_INFORMATION_V2*

Now we check Stack Traces for individual entries and their error codes:
