           Summary: bootstrap failure building libgcc2
           Product: tools
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: llvm-gcc
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: alenhar2 at uiuc.edu


The attched is a reduction of a boot strap failure in llvm-gcc2 on x86/linux.

internal compiler error: in prune_unused_types_update_strings, at dwarf2out.c:14372
"/home/vadve/alenhar2/cfe/build/gcc/cc1" "-g" "-O2"     -o /dev/null min.i

removing either -g or -O2 makes the problem go away.  -O1 still exhibits the
problem.

where min.i is:

  __attribute__ ((__nothrow__)) strtol (__const char *__restrict __nptr, char
**__restrict __endptr, int __base) {  }
  __attribute__ ((__nothrow__)) strtof (__const char *__restrict __nptr, char
**__restrict __endptr) {  }
