Let's clear a common misconception here: the SJLJ EH scheme implemented in C++
doesn't explicitly use __builtin_setjmp/__buitin_longjmp so it won't help to
understand how things work for the case at hand; it's instead a hybrid scheme,

No, it never returns twice through the fallthru edge. It only
returns second time through the abnormal edge virtually to the
ABNORMAL_DISPATCHER and from that through another abnormal edge
to __built

Hi!
I've looked at the spawner_inline.c timeout issue, and it looks like the
problem is that __builtin_setjmp_receiver is a stmt_ends_bb_p call and
insert_backedge_copies then happily inserts statements before the call,
because it can't insert them after the call. But __builtin_setjmp_receiver
is
