[Bug c/28833] New: GCC 4.1.1 ICEs compiling Xorg 6.8.2

["peter at empeg dot com" <gcc-bugzilla@gcc.gnu.org>]

Attached (gzipped) fbmmx.i (from Xorg 6.8.2 xc/programs/Xserver/fb/fbmmx.c)
gives "fbmmx.c:871: internal compiler error: in push_reload, at reload.c:1303"
when compiled with 4.1.1 on i686-linux-gnu. This is probably a regression as
I've previously compiled the same Xorg release fine with 4.1.0.

GCC also emits lots of warnings, but no errors.

--- GCC version

[peter@electronic fb]$ gcc --version
gcc (GCC) 4.1.1

--- GCC configured with

../g*/configure --prefix=/usr --enable-shared --enable-languages=c,c++,java
--enable-threads --enable-__cxa_atexit --with-system-zlib --disable-multilib

--- GCC command to trigger failure

gcc -m32 -c -O2 -O9 -march=pentium4 -mtune=pentium4 -mmmx -msse -msse2 -pipe
-ansi -pedantic -Wall -Wpointer-arith -Wundef    -fno-merge-constants -c  
-mmmx -Winline --param inline-unit-growth=10000  --param
large-function-growth=10000 fbmmx.i
