             Bug #: 52260
           Summary: [4.7 Regression] ICE in clone_tree_hash, at
                    dwarf2out.c:7424
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: doko@gcc.gnu.org

preprocessed source

seen with 20120214 r184236 in stage1 building the debug libstdc++, last
successful build was 20120210 on arm-linux-gnueabi, configured with:

         --enable-libstdcxx-debug
         --enable-libstdcxx-time=yes
         --with-arch=armv7-a
         --with-float=hard
         --with-fpu=vfpv3-d16
         --with-mode=thumb

omitting -gdwarf-4 avoids the ICE.
