Crash happened in all scenarios: using X11 (via framebuffer) and
mozilla, or X11 and sylpheed, or tty and compiling the kernel, or tty
and managing email via courier-imapd-ssl.
Based on this[0] comment, I think that the problem is in libc6.
The machine was working very well, with all software from etch.
A few days ago I decided to use latest kernel from unstable (this is
2.6.24-2) but that kernel isn't compilable on etch because it require
gcc-4.2. So, I updated gcc, g++, binutils, libstdc++, libgcc1 and libc6
from unstable.
After this update nothing worked.
When I switched back to libc6/gcc/g++/libstdc++/libgcc1/binutils from
etch, everything went well.
Currently the machine is running etch. The actual mapping of those
libraries are:
giuseppe@sgi:~$ ldd /usr/bin/sylpheed | grep -E '(libc\.|libstdc\+\+\.|libgcc)'
libc.so.6 => /lib/libc.so.6 (0x2c2a4000)
libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x2c5c8000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x2c718000)
When trying to get back to my original configuration, I switched kernel
to 2.6.23.1 (leaving libraries from unstable) and tried to recompile the
kernel source using make-kpkg or dpkg-buildpackage. What happened was
that many program started segfaulting (signal 11 and 10). Programs like
"diff", "patch", and so on.

This is a boot log when using the kernel whipped with debian unstable.
