             Bug #: 54357
           Summary: ICE in output_pic_addr_const
    Classification: Unclassified
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: alexander.adam@informatik.tu-chemnitz.de


Created attachment 28070
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=28070
File demonstrating the bug.

In the attachment is a very stripped down version of the code that makes gcc
ICE. I tested with version:
     4.1.2.20070115 (prerelease) on SuSE Linux 32 bit
     4.7.1 on Debian (4.7.1-2) 64 bit with -m32-Flag

The command line used to compile the code was:
     gcc -O1 -fPIC -c -m32 -o test.o asm_p_flag_ice.c

This is a very minimalistic example.
It works fine if we use the function address as argument.
It works with other modifiers for the assembler.
It works if -fPIC is ommitted or -O0 is used.

I give here the options that were used to build the gcc bit on Debian:

$ gcc -v
Using built-in specs.
COLLECT_GCC=gcc

$ uname -a

The output, if the file is compiled:

$ gcc -O1 -fPIC -c -m32 -o test.o asm_p_flag_ice.c 
asm_p_flag_ice.c: In function âICE_funcâ:
asm_p_flag_ice.c:15:1: internal compiler error: in output_pic_addr_const, at
