--- Comment #5 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
Thanks, I saw this problem too while compiling chromium but then it went away
and we didn't really managed to simplify it to a testcase.
The problem here is that there is PHI sitting on a EH receiver (from setjmp)
and we are inlining speculatively inlined call that may throw while original
call didn't. It seems to be bug that is there for years. I am not quite sure
what to do in this scenario sort of going out of SSA for this particular symbol
and back to SSA again (that probably would go with markin it for update)
Curiously enough your patch does not contain any calls that ipa-devirt would
change.
I am looking into it
