fatalExecutionEngineError MDA

.NET Framework 4.5

The fatalExecutionEngineError managed debugging assistant (MDA) is activated when a fatal error in the common language runtime (CLR) has been detected. The process will be terminated.

Symptoms

Unexpected process termination. Other symptoms cannot be determined because a CLR failure can occur for a variety of reasons.

Cause

The CLR has been fatally corrupted. This is most often caused by data corruption, which can be caused by a number of problems, such as calls to malformed platform invoke functions and passing invalid data to the CLR.

Resolution

Enabling additional MDAs might help identify the problem. The following MDAs can be particularly helpful in diagnosing the issue:

Effect on the Runtime

This MDA has no effect on the runtime's behavior.

Output

The address of the CLR function that caused the fatal error, the ID of the thread where the error occurred, and the error code.

Configuration

<mdaConfig>
  <assistants>
    <fatalExecutionEngineError />
  </assistants>
</mdaConfig>
