Summary:

Compiling the attached particular piece of code as thumb at -O2 causes the 
compiler to seg fault inside asm_fprintf. It has been reproduced using gcc 
3.3.2 on cygwin and gcc 3.3.1 on macos x. All were compiled using the same 
options.

Release:
gcc 3.3.2 release

Environment:
Linux version 2.4.22-gentoo-r4 (root@varmit) (gcc version 3.2.3 20030422 
(Gentoo Linux 1.4 3.2.3-r3, propolice)) #1 SMP Sat Jan 10 17:26:16 PST 2004

host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: arm-elf
Configured with: ../gcc-3.3.2/configure --prefix=/usr/local/armdev-3.3.2 --
target=arm-elf --program-prefix=arm-elf- --program-suffix=332 --with-newlib --
enable-languages=c
Thread model: single
gcc version 3.3.2

to repeat (where pco_trace.i is the attached file):
arm-elf-gcc332 -v --save-temps -c -mthumb -fno-builtin -O2 -W -Wall -mthumb-
interwork -fsigned-char -funsigned-bitfields -o pco_trace.o pco_trace.i

output is:
