MSVCR80.dll crash

Anyone cast any light on this, I've got an app running C#/.Net which is calling out to a COM component, and it keeps running for a bit, then crashing with an exception in MSVCR80.dll . I've tried this on several different PC's with Vista/Win7/Win8.1 all with the same problem.
Any ideas?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You've not made it clear if you are a developer or a user. If you are a developer:

Step 1: generate a dump file
Step 2: use something like WinDBG to analyse the dump file to see what is causing the crash

Sorry, been very tied up, but this is still an issue (its just a process I only run once a month), but I am going to get the dump.
