           Summary: 3.3: ICE with -gstabs when including STL headers
           Product: gcc
           Version: 3.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: lloyd at randombit dot net
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: i686-linux
  GCC host triplet: i686-linux
GCC target triplet: i686-linux

Including virtually any STL header and attempting to compile with -gstabs with
GCC 3.3 causes an ICE on x86/Linux. I'm using glibc 2.2.5 and binutils
2.11.93.0.2, though I doubt either is relevant here. Using other debug flags,
like -gstabs+, -gdwarf, -gdwarf-2, etc, seems to work fine.

$ cat stabsbug.cpp 
#include <vector>

int main() { return 0; }
