Heap corruption when profiling .Net App

christensen__david — Wed, 19 Sep 2018 13:03:56 GMT

I'm regularly seeing a problem with .Net (C#) apps which run perfectly well outside VTune, but which when I attempt to profile them crash almost immediately with a stack trace in RtlFree and a message of heap corruption.

Is this a known problem? Is there a workaround?

This is using Vtune 2018 update 3.

Thanks

David

Hello David,

Is there a chance to get your app to reproduce the issue locally?

Thanks, Denis

The full app is commercially

The full app is commercially sensitive, but I'll try to produce a cut-down version that exhibits the problem.

Regards

David
