One from memory, not from disk.  Usually this will be
linux-gate.so.1
or something like that; a virtual DSO provided by the
kernel.

I'm not sure why it would fail.  What platform and kernel
version?

Ubuntu Gutsy Gibbon, 2.6.22-6-generic i686 GNU/Linux.

Since Gutsy Gibbon is still in beta, it might be indeed the
cause of all 
trouble. Should I downgrade to a previous kernel version or
is there any 
other solution?

by the way,
ldd ./program gives:
         linux-gate.so.1 =>  (0xffffe000)
         libstdc++.so.6 => /usr/lib/libstdc++.so.6
(0xb7de1000)
         libm.so.6 => /lib/tls/i686/cmov/libm.so.6
(0xb7dba000)
         libgcc_s.so.1 => /lib/libgcc_s.so.1
(0xb7dae000)
         libc.so.6 => /lib/tls/i686/cmov/libc.so.6
(0xb7c6a000)
         /lib/ld-linux.so.2 (0xb7eec000)
