 Posted: Thu Feb 10, 2011 4:13 pm Post subject: Fatal Execution Engine Error |
 |
|
Hi,
I have a WPF application developed with Visual Studio 2008 in .net 3.5 SP1.
When I ran the profiler, my application crashes.
I have 2 events in the windows Event Viewer:
- .NET Runtime version 2.0.50727.4952 - Fatal Execution Engine Error (000007FEF86DFA42) (80131506)
- Faulting application name: Toto.exe, version: 1.0.0.0, time stamp: 0x4d53ec84
Faulting module name: mscorwks.dll, version: 2.0.50727.4952, time stamp: 0x4bebe78c
What should I do to profile my application ?
Thanks for your help ! |

Just to double check, is this fatal error you get happening when you use ANTS Performance profiler? The error signature gave me quite a few hits in support case history, but all for memory profiler.

Yes, I have this error just when I launch my app with ANTS Performance profiler. My app works fine without the profiler.
I have no more logs in my event viewer... |

Can you attach a debugger to the application as you are profiling it?

Just to follow up, if your WPF application does not crash right away, it is possible to attach Visual Studio or another debugger to the process after it has been launched by Profiler. Debugging should hopefully pinpoint some kind of error we can troubleshoot. Have you tried that?
