re PR gcov-profile/64634 (gcov reports catch(...) as not executed)
PR gcov-profile/64634
* tree-eh.c (frob_into_branch_around): Fix up typos
in function comment.
(lower_catch): Put eh_seq resulting from EH lowering of
the cleanup sequence after the cleanup rather than before
it.
* g++.dg/gcov/gcov-15.C: New test.
