This ICE stopped to appear on trunk with r162019:
http://gcc.gnu.org/ml/gcc-cvs/2010-07/msg00373.html
http://gcc.gnu.org/ml/gcc-patches/2010-07/msg00827.html

Applying the generic bits of that to current 4.5 stops the ICE there too.  I
can't say if r162019 is a genuine bug fix or merely improves things a bit so
that this test case no longer triggers the ICE.

Oops, that was with a locally modified 4.5-20100902.  A vanilla 4.5-20100902
still ICEs.

Some random config of the linux kernel, as of 2.6.36-rc3 results on the
following

stat.c: In function 'show_stat':
stat.c:123:1: error: unable to find a register to spill in class 'FP_REGS'
stat.c:123:1: error: this is the insn:
(insn 43 49 50 3 stat.c:43 (set (reg:DI 281 [ D.14392_45->cpustat.user ])
(mem/s:DI (plus:SI (reg:SI 25 %i1 [orig:500 __ptr ] [500])
(reg:SI 15 %o7 [orig:128 D.16865 ] [128])) [7
D.14392_45->cpustat.user+0 S8 A64])) 46 {*movdi_insn_sp32} (expr_list:REG_EQUIV
(mem/s:DI (plus:SI (reg:SI 25 %i1 [orig:500 __ptr ] [500])
(reg:SI 15 %o7 [orig:128 D.16865 ] [128])) [7
D.14392_45->cpustat.user+0 S8 A64])
(nil)))

the (already) attached testcase still fails with gcc 4.5.2.
