Bootstrap ICE in main trunk (latest).

[Klaus-Georg Adams <Klaus-Georg dot Adams at chemie dot uni-karlsruhe dot de>]

When I bootstrap the latest egcs (as of gcc/ChangeLog Version 1.1910)
with BOOT_CFLAGS="-g -O4" it dies with a Signal 11 on objc/sendmsg.c:

./xgcc -v -B./  -DIN_GCC   -DUSE_GNULIBC_1 -W -Wall -g -O4 -I./include  -I. -I../../egcs-cvs/gcc -I../../egcs-cvs/gcc/config -Iobjc -c ../../egcs-cvs/gcc/objc/sendmsg.c -o objc/sendmsg.o -save-temps
