Description

Mu2e reports a situation where an error occurring while loading a GDML file results in ROOT attempting to double-unlock a mutex. Although this is an error in how exceptions are handled in ROOT's Clang, Philippe Canal reports that it can safely be ignored:

So if you could filter out (i.e. just print an error message or warning) anything from the regex "'T.*Lock::WriteUnLock" (or TReentrantRWLock::WriteUnLock), it solve the problem.
