OK, so that's where to look for fixing this - but if a spurious / missing
exception issue is waiting a while for a fix, it's best to file a bug in
Bugzilla (that's a good idea anyway) and use e.g. UNDERFLOW_EXCEPTION_OK
in the relevant tests, with a comment saying the exception is spurious /
missing and pointing to the open bug, so that the known problem doesn't
cause testsuite failures while open.
