--- Comment #4 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
FWIW, removing 'if (can_throw_internal (insn)) { ... }' code in
ira-lives.c:process_bb_node_lives introduced by fix for PR 38811 improves this
testcase and doesn't seem to introduce testsuite regressions on both 32 and
64-bit x86, but this might just mean that there's not enough runtime testcases
for catching exceptions. The place for a proper fix may be elsewhere, I don't
know what special considerations are required for throwing calls.
