Package: gcc-4.0 Version: 4.0.2-8 Severity: important I am currently trying to build the glibc with gcc-4.0 instead of gcc-3.4 on all arches. On m68k, I get an ICE:
(unstable)[EMAIL PROTECTED]:~$ gcc-4.0 system.c -O -c -g -fomit-frame-pointer -o system.o system.c: In function '__libc_system': system.c:16: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://gcc.gnu.org/bugs.html> for instructions. For Debian GNU/Linux specific bug reporting instructions, see <URL:file:///usr/share/doc/gcc-4.0/README.Bugs>.
