cc1obj segfaults when building libobjc/linking.m on a linux-2.2.9
system (glibc-2.1). That's the first ObjC file which is compiled.
../configure --with-gcc-version-trigger=/home/doko/packages/egcs/gcc-snapshot-19990518/gcc/version.c --host=i486-debian-linux-gnu -v --prefix=/usr/lib/gcc-ss --enable-shared --with-fast-fixincludes --enable-threads --enable-java-gc=boehm --enable-objc-gc --norecursion
The snapshot comes from the CVS gcc-2_95_branch. The 19990502 snapshot
bootstrapped ok.
