> Can you please verify?

Yes, this fixes the test case.  However if the orginal test case is valid
fortran we probably need to fix something else. Paul Thomas was noticing a
similar problem with his Finalization patches.  He was doing the finalizati=
on
inside trans_transfer or similar so it was blocking on a mutex trying to
finalize in the middle of an I/O operation.

So in this case, my guess is the merge expression needs to be resolved befo=
re
the translation phase.=
