            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

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.
