Hi list! I am running CentOS 4.1 x86_64 on an Athlon64. The box was installed only yesterday. Yesterday I was still able to compil stuff, yesterday even the tiniest and simplest programs fail to compile always with internal compiler error: Segmentation fault. For example: make -C /usr/src/linux-2.6 SUBDIRS=/tmp/bristuff-0.2.0-RC8n/qozap ZAP=-I/tmp/bristuff-0.2.0-RC8n/zaptel-1.0.9 modules make[1]: Entering directory `/usr/src/kernels/2.6.9-11.EL-x86_64' CC [M] /tmp/bristuff-0.2.0-RC8n/qozap/qozap.o In file included from include/linux/types.h:13, from include/linux/kernel.h:13, from /tmp/bristuff-0.2.0-RC8n/qozap/qozap.c:13: include/linux/posix_types.h:41: internal compiler error: Segmentation fault The 'funny' thing is that the problem is in different modules for each program like: /usr/include/stdlib.h:757: internal compiler error: Segmentation fault include/linux/posix_types.h:41: internal compiler error: Segmentation /usr/include/gconv.h:72: internal compiler error: Any ideas as to what might be broken on the box? Thanks! Remco
