(preprocessed output from a file that formed part of audacious) with the
following command

gcc -fPIC -DPIC -g -O2 -std=gnu99 -pipe -pthread -c -xcpp-output

on debian sparc sid (debian gcc version 4.6.2-15, triplet sparc-linux-gnu)
produces.

ui_fileopener.c:200:1: internal compiler error: output_operand: invalid
expression as operand
Please submit a full bug report,
with preprocessed source if appropriate.

Preprocessed source stored into /tmp/ccxHh7Af.out file, please attach this to

If the optimisation level is dropped to -O1 or -fPIC is removed from the
command line the file builds successfully.

gcc-4.5 (debian gcc version 4.5.3-12) does not exhibit the bug.
gcc-snapshot ((Debian 20120128-1) 4.7.0 20120128 (experimental) [trunk revision
183664]) also does not exibit the bug.
