You are using an modified compiler from Redhat you should report it to them.

a reduced test case
A reduced test case which ICEs with -funroll-loops -ffast-math -O2.
It fails with 4.3/4.4 compilers and doesn't fail with 4.2.

------- Comment #4 from kkojima at gcc dot gnu dot org 2008-10-09 04:50 -------
The regmove pass changes insns in .160r.ce2 dump
(insn 285 77 78 6 foo.C:14 (set (reg/f:SI 260)
(reg/f:SI 269 [ ivtmp.66 ])) -1 (expr_list:REG_DEAD (reg/f:SI 269 [
ivtmp.66 ])
(nil)))
(insn 78 285 79 6 foo.C:14 (parallel [
(set (reg:SF 280)
(mem:SF (post_inc:SI (reg/f:SI 260)) [2 S4 A32]))
(use (reg/v:PSI 151 ))
(clobber (scratch:SI))
]) 205 {movsf_ie} (expr_list:REG_INC (reg/f:SI 260)
(nil)))
to
(insn:HI 285 77 78 6 foo.C:14 (set (reg/f:SI 269 [ ivtmp.66 ])
(reg/f:SI 269 [ ivtmp.66 ])) -1 (nil))
(insn:HI 78 285 79 6 foo.C:14 (parallel [
(set (reg:SF 280)
(mem:SF (post_inc:SI (reg/f:SI 269 [ ivtmp.66 ])) [2 S4 A32]))
(use (reg/v:PSI 151 ))
(clobber (scratch:SI))
]) 205 {movsf_ie} (expr_list:REG_INC (reg/f:SI 260)
(nil)))
in .162r.regmove.
It seems that regmove forgets to update the register 260 to 269
in REG_INC note of the insn 78 and this wrong REG_INC note causes
the ICE.
Now I'm testing the attached patch, for 4.3-branch.
BTW, please use the compiler based on the vanilla FSF tree
for bugzilla as Andrew has pointed out already.
