            Bug ID: 58990
           Summary: G++ generates duplicate labels for linux 32-bit when
                    optimization+LFS is enabled
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: novulae at hotmail dot com

GCC 4.4.5 compiles this code without issue, GCC 4.6.0 produces the below error,
as does GCC 4.8.0. This happens on linux 32-bit, but not 64-bit. I haven't
tried to see if g++ -m32 has the same issue when on linux 64-bit.

$ cat test.cpp
#include <sys/stat.h>
#include <stdint.h>

void *foo(bool var) {
  if (var) return (void*)(intptr_t)&stat;
  return (void*)(intptr_t)&stat64;
}

$ g++ -O1 -D_FILE_OFFSET_BITS=64 -c test.cpp
/tmp/ccI8JqrP.s: Assembler messages:
/tmp/ccI8JqrP.s:22: Error: symbol `stat64' is already defined
