Michael Matz <matz at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|RESOLVED |REOPENED CC| |matz at gcc dot gnu.org Resolution|FIXED | --- Comment #6 from Michael Matz <matz at gcc dot gnu.org> 2012-01-25 15:13:35 UTC --- This testcase still segfaults in the same way. The problem this time is in removing regions without landing pads (remove_unreachable_handlers_no_lp), which also happily removes regions that still are referenced by resx instructions. % cat pr48794-2.f90 !
