I get the same thing when I use r171282 of FSF 4.5 branch.
arm-none-linux-gnueabi-gcc pr48325.c -mfloat-abi=softfp -mfpu=neon -O1
pr48325.c: In function 'test':
pr48325.c:19:1: error: insn does not satisfy its constraints:
(insn 40 38 26 2
/work/ianbol01/cross-build/gcc45-r171282-thumb/arm-none-linux-gnueabi/tools/lib/gcc/arm-none-linux-gnueabi/4.5.3/include/arm_neon.h:10277

{*neon_movoi} (expr_list:REG_INC (reg/f:SI 3 r3 [151])
(nil)))
pr48325.c:19:1: internal compiler error: in reload_cse_simplify_operands, at
postreload.c:396
Here is the command-line just for cc1:
cc1 -quiet pr48325.c -mfloat-abi=softfp -mfpu=neon -marm -mcpu=cortex-a9 -O1
Doesn't work for thumb either.
It also fails on trunk.
There are two other bugs in flight that manifest in
reload_cse_simplify_operands: PR48250 (broke on trunk for EABI, works on 4.5
for EABI) and PR42949 (works on EABI for trunk and gcc4.5, broke for OABI).
I do not know if they are duplicates of each other, or if there are two or more
separate bugs causing this.
