Confirmed. Note that it does not happen for -marm.
Full compilation command-line:
cc1 -fpreprocessed 49049.i -quiet -dumpbase 49049.i -mthumb -mcpu=cortex-a9
-mfloat-abi=softfp -mfpu=vfpv3-d16 -auxbase 49049 -O3 -version -o 49049.s

Thanks for confirming that.
If I try "-marm -mcpu=arm7tdmi" I can get the ICE, but not with "-marm
-mcpu=cortex-a9".

[ http://bugs.debian.org/630746 ]
looks like a regression in current 4.6 branch and the trunk, works with current
4.4 and 4.5 branches. The volume.i builds with -O2 instead of -O1 (the Debian
compiler targets armv4 by default).
$ gcc -g -O -c volume.i../vol/volume.c: In function 'VShutdown_r':
../vol/volume.c:1320:1: error: insn does not satisfy its constraints:
(insn 1117 1116 669 56 (set (reg:SI 8 r8 [561])
(minus:SI (const_int 12 [0xc])
(const_int 5784 [0x1698]))) ../vol/volume.c:1409 29
{*arm_subsi3_insn}
(nil))
