Hi, since 1 or 2 days i get segmentation faults on 2 computers and logs
say nothing. memtest gives no errors!

with layman:

# layman -S
Speicherzugriffsfehler
#

with "emerge progname":

random segfaults, especially at the end of emerge-process or cleanups.
mostly bigger programms like php,sandbox,portage,openssl,gcc itself

info:

ati-drivers 8.41.7

# gcc --version
gcc (GCC) 4.2.2 (Gentoo 4.2.2 p1.0)
