[Bug c++/48999] New: [4.7 Regression] FAIL: g++.dg/torture/20090706-1.C due to an ICE on *-*-darwin*


http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48999

           Summary: [4.7 Regression] FAIL: g++.dg/torture/20090706-1.C due
                    to an ICE on *-*-darwin*
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: dominiq@lps.ens.fr

Between revisions 173448 and 173467 compiling g++.dg/torture/20090706-1.C gives
and ICE on *-*-darwin* (see
http://gcc.gnu.org/ml/gcc-testresults/2011-05/msg00614.html and
http://gcc.gnu.org/ml/gcc-testresults/2011-05/msg00654.html ). The ICE is

/opt/gcc/work/gcc/testsuite/g++.dg/torture/20090706-1.C: In constructor
'CanonicalCentering<Dim>::CanonicalCentering() [with int Dim = 2]':
/opt/gcc/work/gcc/testsuite/g++.dg/torture/20090706-1.C:41:37: internal
compiler error: in bitmap_first_set_bit, at bitmap.c:782

Candidate revisions are 173449 (unlikely: the ICE occurs with both gcc and
g++), 173451, 173465 (unlikely: objc stuff), and 173467.
