--- Comment #3 from Martin Jambor <jamborm at gcc dot gnu.org> ---
I believe our tester has hit this again recently:

arm-linux-gnueabi-gcc
/home/worker/buildworker/tiber-option-juggler/build/gcc/testsuite/gcc.c-tor=
ture/compile/packed-aligned-1.c
-mcpu=3Dcortex-r4f -fno-tree-coalesce-vars -O2
--param=3Dhot-bb-frequency-fraction=3D0

results in an ICE in output_move_double, at config/arm/arm.cc:20091

The backtrace is similar:

0xdeadbeef output_move_double(rtx_def**, bool, int*)
/home/worker/buildworker/tiber-gcc-trunk-arm/build/gcc/config/arm/arm.cc:20=
091
0xdeadbeef final_scan_insn_1

0xdeadbeef final_scan_insn(rtx_insn*, _IO_FILE*, int, int, int*)
