Subject: [Bug middle-end/53460] New: Internal compiler error: in calc_dfs_tree, at dominance.c:395
Date: Wed, 23 May 2012 15:34:00 -0000	[thread overview]
Message-ID: <bug-53460-4@http.gcc.gnu.org/bugzilla/> (raw)

             Bug #: 53460
           Summary: Internal compiler error: in calc_dfs_tree, at
                    dominance.c:395
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: middle-end
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: linux@carewolf.com


Compiling webkit with either -fprofile-generate or -fprofile-use will cause GCC
to ICE on several different files. Under any other compile flags GCC compiles
the same files without any problems.

There are one other open bug that ICE at the same place in GCC, but seeing that
several older bugs have the same line, I assume that is no guarantee that the
bug is the same, and the other bug is not related to profiling.

I have included two examples, but have not reduced them.
