Yes, I uncommented the "disk / 10000" line. This is actually the change
that trigger the segfault.

Same problem

Same problem

Here is the backtrace:

Program received signal SIGSEGV, Segmentation fault.
0x77c20e60 in getmntent_r () from /lib/tls/libc.so.6

I haven't the time to dig more into the problem, but it *may* be a bug
in the glibc.
