This looks really bad (for me). After running
some programs (like mc - midnight commander) give a segmentation fault (yeap, that's my nick, ironic...), and I cannot emerge anything (emerge also fails with a segmentation fault. After some research I found out that this could be related to glibc, so here is some info:

Here is the output of mc run in gdb:
