Moles crashing when unit test debugging is being stopped

Question

I'm using Pex and Moles Power Tools 0.94.51023.0 64-bit (en_visual_studio_2010_pex_0.94.51023.0_power_tools_x64_598803.exe) in Visual Studio 2010 SP1 (Windows 7 Enterprise 64-bit, all updates installed via Windows Update). Project is .NET 2.0, tests are running in 32-bit mode set explicitly in settings. When run, everything is ok and no errors occur. But when I run tests in debug mode and stop before they finish, Moles are crashing:

Attached debugger and got more detailed information:

The test adapter 'MolesAgentAdapter' threw an exception while running test 'My_Test_Method_Name'. Failed to read from an IPC Port: The pipe has been ended.

When test is run to the end, no crash occurs. Already tried to reinstall .NET Framework and Moles, no success resolving this problem. Any ideas what is causing/how to fix this issue? Proxy and IPC connections shown are very weird. Thanks in advance.

Answer 1

Issue was resolved during project upgrade which resulted in phasing out Moles and substituting them to Fakes.
