Bug ID: 59241 Summary: ICE in initialize_flags_in_bb Product: gcc Version: 4.9.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: tree-optimization Assignee: unassigned at gcc dot gnu.org Reporter: kilobyte at angband dot pl Created attachment 31267 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=31267&action=edit deltaed test case When running g++ -O2, in a trunk snapshot 20131121-1 (from Debian) on attached code, I get: internal compiler error: in initialize_flags_in_bb, at tree-into-ssa.c:459 void MenuDescriptor::init() ^ Lower optimization levels compile ok, so does any prior version, including snapshot 20131021-1 from a month ago. I don't know the build rituals for vanilla gcc (using Matthias Klose's snapshots instead), so sorry for not bisecting myself.
