             Bug #: 52630
           Summary: [4.7 regression] ICE when compiling ppl-0.12 testsuite
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: major
          Priority: P3
         Component: middle-end
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: matt@use.net


While PPL 0.12 itself built okay, it's "make check" target did not. I bootstrap
all required GCC libraries with a given GCC release, and run all their
testsuites. It usually weeds out subtle wrong-code issues and ICEs. GMP, MPC,
CLOOG-ISL, and MPFR were all fine.

I cannot reproduce.  Please post the output of 'gcc -v' and a backtrace.
