Random Crashes of ArcMap 10 (using Custom Extension)

I use a Custom ArcMap Extension. I also use Stereo Analyst for ArcGIS Extension.

When running ArcMap 10 (with the two extensions), I get random, non-reproducible crashes. With ArcMap 9.3.1 these crashes didn't occur.

Faulting application name: ArcMap.exe, version:, time stamp: 0x4d9bad9f
Faulting module name: MSVCR90.dll, version: 9.0.30729.6161, time stamp: 0x4dace5b9
Exception code: 0xc0000417
Fault offset: 0x0006ccd5
Faulting process id: 0xc3c
Faulting application start time: 0x01cc7771cbb9ef76
Faulting application path: C:\Program Files (x86)\ArcGIS\Desktop10.0\Bin\ArcMap.exe
Faulting module path: C:\Windows\WinSxS\x86_microsoft.vc90.crt_1fc8b3b9a1e18e3b_9.0.30729.6161_none_50934f2ebcb7eb57\MSVCR90.dll
Report Id: 3c6c1f96-e365-11e0-bb0f-00199991eda6

I assume the following:
- The crash happens in MSVCR90.dll, which is a Microsoft C runtime library, part of Microsoft® Visual Studio 2008
- The error must be somewhere below, i.e. in the ArcMap or Stereo Analyst Code, not in my code

Are my assuptions right?
What can I do?
