[Bug rtl-optimization/43484] New: GCC 4.5 does not build gamess, zeusmp on powerpc -m32 with loop unrolling

["meissner at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

If I build gamess and zeusmp with my normal spec optimization options, I get an
internal compiler error in the change_address_1 function in emit-rtl.c, due to
an address needing fixup has been generated after register allocation has been
done.  I have narrowed the options down to -m32 -mcpu=power4 -O2 -funroll-loops
that causes the problem.  I was able to build all of spec with the normal
options on March 3rd.

foo.f: In function ?gcidav?:
foo.f:670:0: internal compiler error: in change_address_1, at emit-rtl.c:1912
Please submit a full bug report,
with preprocessed source if appropriate.
