> Description:
After updating netbsd current source tree on 30.09.2011 hpcarm compilation fails in \
lib/csu/arm_elf/crt0.o:
dependall ===> lib/csu/arm_elf
compile arm_elf/crt0.o
arm--netbsdelf-gcc: Internal error: Segmentation fault (program as)
Please submit a full bug report.
See <http://www.NetBSD.org/Misc/send-pr.html> for instructions.

*** Error code 1
According to the core dump the backtrace is:
#0 0x08074ad1 in arm_cleanup ()
#1 0x0805e32f in read_a_source_file ()
#2 0x0804afeb in perform_an_assembly_pass ()
#3 0x0804bd25 in main ()
> How-To-Repeat:
The simpliest way to reproduce the problem is:
1. Build hpcarm toolchain with: ./build.sh -N 1 -u -U -O ../obj-hpcarm -T \
../tools-hpcarm -m hpcarm tools 2. $echo "__asm(\"nop\");" > test.c
3. arm--netbsdelf-gcc test.c -o test.o
