Since the upgrade to gcc-4.3, gcc has started to ICE on selected
packages. After some debugging, all cases so far seem to relate
to using -funroll-loops, so I'll start putting all ICE's to same
bugreport.

Using built-in specs.
Target: arm-linux-gnueabi
Configured with: ../src/configure linux gnueabi
Thread model: posix
gcc version 4.3.1 20080401 (prerelease) (Debian 4.3.0-3)

libcoveb:

coveb-tree.i:

$ gcc-4.3 -S -g -O2 -funroll-loops coveb-tree.i
../../../src/coveb-tree.c: In function 'coveb__ibq_remove':
../../../src/coveb-tree.c:1053: internal compiler error: Segmentation
fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.3/README.Bugs> for instructions.

Removing -funroll-loops make compile succeed.

john:

$ gcc -S -Wall -O2 -fomit-frame-pointer -funroll-loops DES_bs.i
DES_bs.c: In function 'DES_bs_cmp_all':
DES_bs.c:175: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.3/README.Bugs> for instructions.

Removing -funroll-loops make compile succeed.

pymol:

$ gcc -g -O2 -fwrapv -funroll-loops -S Match.i
layer0/Match.c: In function 'MatchAlign':
layer0/Match.c:578: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.3/README.Bugs> for instructions.

removing either -funroll-loops or -fwrapv makes compile succeed.

openarena:

$ gcc -S -O3 -ffast-math -funroll-loops files.i

code/qcommon/files.c: In function 'FS_Seek':
code/qcommon/files.c:1454: internal compiler error: Segmentation fault
Please submit a full bug report,
