I think there is more going on here than gcc-config. I encountered the
very same problems on my machine only after having done an `emerge -uDN
world` and only having one compiler, gcc-4.4.4-r1, on the system.
Hans, I was able to fix gcc-config with `gcc-config -f 1`. However not
only is /usr/bin/gcc seg faulting but
/usr/x86_64-pc-linux-gnu/gcc-bin/4.1.1/gcc is also insomuch that I can't
even compile this simple program without a segmentation fault,
int main()
{
return 0;
}
yet even after having done `gcc-config -f 1` the profile may be correct
according to gcc-config,
# gcc-config -l
[1] x86_64-pc-linux-gnu-4.1.1 *
but the compiler still gives segmentation faults. This totally baffles
me as `ldd /usr/x86_64-pc-linux-gnu/gcc-bin/4.1.1/gcc` shows that gcc
only links in
libc.so.6 => /lib/libc.so.6 (0x00002aadee5c4000)
/lib64/ld-linux-x86-64.so.2 (0x00002aadee4a6000)
and the mtimes on all three files (gcc, libc.so, ld-linux-x86-64.so)
are according to ls:
lrwxrwxrwx 1 root root 23 Sep 4 22:39
/usr/x86_64-pc-linux-gnu/gcc-bin/4.1.1/gcc -> x86_64-pc-linux-gnu-gcc
-rwxr-xr-x 1 root root 140K Sep 4 22:39
/usr/x86_64-pc-linux-gnu/gcc-bin/4.1.1/x86_64-pc-linux-gnu-gcc
-rwxr-xr-x 1 root root 1.4M Oct 1 22:54 /lib64/libc-2.5.so
lrwxrwxrwx 1 root root 11 Oct 1 22:54 /lib64/libc.so.6 -> libc-2.5.so
-rwxr-xr-x 1 root root 140K Oct 1 22:54 /lib64/ld-2.5.so
lrwxrwxrwx 1 root root 9 Oct 1 22:54 /lib64/ld-linux-x86-64.so.2 ->
ld-2.5.so
These files are clearly much older than yesterday which is when I began
having these gcc problems. Unfortunately I'm still stumped and am
without a working gcc in the meantime.
