[Bug tree-optimization/20474] New: ICE while compiling openmotif-2.2.3 with -ftree-vectorize

[zlynx at acm dot org]

I was updating my Gentoo installation with the latest and got an internal
compiler error in openmotif.  This happened first with Gentoo's GCC version
4.0.0_beta20050305.  I then CVS'd the latest GCC version and got the same
error with that.

gcc version 4.1.0 20050314 (experimental)
configured with: ../configure --prefix=/opt/gcc-4.0 --with-system-zlib
--disable-checking --disable-werror --disable-libunwind-exceptions
--disable-multilib
--with-gcc-version-trigger=/home/lynx/Desktop/working/gcc/gcc/version.c
--enable-languages=c,c++,java,objc : (reconfigured) ../configure
--prefix=/opt/gcc-4.0 --with-system-zlib --disable-checking --disable-werror
--disable-libunwind-exceptions --disable-multilib
--with-gcc-version-trigger=/home/lynx/Desktop/working/gcc/gcc/version.c
--enable-languages=c,c++

How-To-Repeat:
Command:
# gcc -O3 -ftree-vectorize pack.c
Output:
pack.c: In function 'PackString':
pack.c:865: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

I will attach pack.i
