Access violation - coreclr!EventPipeEventSource::SendProcessInfo+0x135 #12656
Description
When running the DefaultInterfaces test with AutoTrace, we hit an access violation in EventPipeEventSource::SendProcessInfo.
In particular, the code was trying to dereference pCommandLine obtained from GetManagedCommandLine which returned NULL because the backing field s_pCommandLine is never saved using SaveManagedCommandLine in the interop scenario.
