Access Violation On Vista Startup

Question

I occasionally get a strange unhandled access violation when my .NET application is started automatically on startup (using a shortcut in the "Startup" folder) by Windows Vista. I have not seen this error when I start the executable manually. It happens randomly and I have yet to be able to reproduce the issue reliably.

Here's the message I get:

Unhandled exception at 0x6f303dea in {executable name}.exe: 0xC0000005: Access violation reading location 0x0000000c.

Call stack:

mscorwks.dll!6f303dea()
[Frames below may be incorrect and/or missing, no symbols loaded for mscorwks.dll]
kernel32.dll!7780907a()
mscoree.dll!6ff47c24()
kernel32.dll!7780d0e9()
ntdll.dll!778e19bb()
ntdll.dll!778e198e()

Since mscorwks.dll is related to the CLR, I think this might be a bug in the CLR. Any ideas on why this might be happening and how to fix it?

It is recommended that you use WER to collect process crash dump. Please select Full Dump option and then you can use WinDBG to debug the dump.
