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