Question

I have been getting a stackoverflow exception in my program which may be originating from a thirdparty libary, microsoft.sharepoint.client.runtime.dll.

Using adplus to create the crash dump, I’m facing the problem that I’m struggling to get any information from it when i open it in windbg. This is what I get as a response:

> 0:000> .restart /f

Any ideas as to how i can get more information from the dump, or how to use it to find where my stackoverflow error is occuring?

Answer 1

The problem you are facing is that the process is 32-bit, but you are running on 64-bit, therefore your dump is a 64-bit dump. To make use of the dump you have to run the following commands:

.load wow64exts
.effmach x86
!analyze -v

The last command should give you a meaningful stack trace.
