[Bug c/42860] New: ICE in gcc-4.4.3

["ronis at ronispc dot chem dot mcgill dot ca" <gcc-bugzilla at gcc dot gnu dot org>]

I've just upgraded to 4.4.3 and tried a fresh build of mesa's git/master.  I
get an ICE as:

/usr/bin/gcc -I../../include -march=native -msse2 -mfpmath=sse -O3 -ffast-math
-funroll-loops -fomit-frame-pointer -floop-interchange -floop-strip-mine
-floop-block -Wall -Wmissing-prototypes -std=c99 -ffast-math
-fvisibility=hidden -fno-strict-aliasing  -fPIC  -DUSE_X86_ASM -DUSE_MMX_ASM
-DUSE_3DNOW_ASM -DUSE_SSE_ASM -D_GNU_SOURCE -DPTHREADS -DHAVE_POSIX_MEMALIGN
-DUSE_EXTERNAL_DXTN_LIB=1 -DIN_DRI_DRIVER -DGLX_DIRECT_RENDERING
-DGLX_INDIRECT_RENDERING -DHAVE_ALIAS  clip.c -L../../lib -lglut -lGLU -lGL 
-lm -o clip
checker.c: In function 'main':
checker.c:129: internal compiler error: in expand_scalar_variables_expr, at
graphite.c:4295
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
gmake[2]: *** [checker] Error 1
gmake[2]: *** Waiting for unfinished jobs....
gmake[2]: Leaving directory `/home/ronis/Project/notar/X/mesa/progs/redbook'

I recompiled with --save-temps and will upload the .i file.

Removing the -floop-interchange -floop-strip-mine -floop-block flags "fixes"
the problem

Finally, I'm quite sure that I reported something similar to this in the past,
and that it was supposedly fixed (I can't find it in bugzilla though).
