FIX: The CLR fails with a fatal execution engine error, and a crash occurs when you run an application by using the .NET Framework 2.0 Service Pack 2

View products that this article applies to.

SYMPTOMS

The common language runtime (CLR) fails with a fatal execution engine error, and a crash occurs when you run an application by using the Microsoft .NET Framework 2.0 Service Pack 2 (SP2). For example, this problem occurs when you start World Wide Web Publishing Service (W3SVC) on a server that is running Microsoft Exchange Server 14, and then submit requests to Exchange Web Services. When this problem occurs, you may experience the following symptoms:

In the Windows Event Viewer, you see a ".NET Runtime" event in the Application log that includes one or more of the following:
- Incorrectly committed to using native image for <assembly>
- COR_E_EXECUTIONENGINE
- 0x80131506
When Fusion logging is turned on, the last Fusion log that is generated in the default category contains the following information at the end of the log:
LOG: Found assembly by looking in the GAC.
LOG: Binding succeeds. Returns assembly from <path of assembly>.
LOG: Assembly is loaded in <LoadFrom or default> load context.
When you run the application under the Windows Debugger before the crash, you find that the CLR writes the following message to the debugger:
Rejecting native image because dependency is not native.

Back to the top

CAUSE

If an assembly that has a native image in the global assembly cache (GAC) is loaded as a dependent bind of an assembly through the LoadFrom method for the first time, Fusion logging will correctly find the assembly. The native image is never returned to the caller, although it is recorded in the load context.
