ExportToStream crashing application with AccessViolation error

33 Views

Hello. I have an application we've written which is using Crystal XI and we're experiencing a very disconcerting error.

Our application is .NET 2.0 and the XI libraries are the most recent release. I think SP4.5? We are very careful to immediately dispose of any crystal objects/resources before we move on to doing the next extract, so the amount of time the crystal libraries are in memory is limited per each iteration of the extract.

I have an open support case for this "Incident 3238538 / 2010 / ExportToStream is crashing randomly" but I don't feel like I'm getting anywhere with it and it's been ongoing for months.

Anyway, I was able to attach the DebugDiag x86 program to an affected system and capture a .dmp file. When I ran the analysis on that file, it mentions an access violation exception occurring in strncpy. (See below)

This error occurs intermittently and does not appear to be data related, as the same extract can run other times without issues, and I haven't been able to pinpoint any single cause. (which makes testing for this nearly impossible)

Apart from the application crashing, windows pops up a debugger screen, saying 'Application has encountered an error and needs to close' which a user must interact with or else the process never ends. I would like to stop this behavior.

I did a ton of reading about unmanaged exceptions on unmanaged threads and I cant find any solution for how to catch exceptions of this kind within .NET.

I've created a C++ library which creates a thread, and then generates an Access Violation in strncpy. Every attempt I've made to catch the error has been met with failure. Does anyone have any clues on what I can do to achieve this??
