Hi,
during cross compilation on amd64 host to arm target I get the followng ICE:
arm-v4t-linux-gnueabi-gcc -c -D_GNU_SOURCE -I proc -isystem
/home/mkl/pengutronix/phytec/OSELAS.BSP-phyCORE-trunk/platform-phyCORE-i.MX27-glibc-2.8/sysroot-target/include
-isystem

proc/sysinfo.c: In function 'get_pid_digits':
proc/sysinfo.c:896: internal compiler error: Segmentation fault
same with -v:
arm-v4t-linux-gnueabi-gcc -c -D_GNU_SOURCE -I proc -isystem
