As I said since we went from libc5 to libc6, all libcs have been
backward ABI compatible. So, it makes perfect sense that the binary works.

Since you are calling getpid() after fork, it is normal that the error
is not signalled before, symbols are only resolved at run-time, when
they are use.

As long as you are comparing the wrong binaries. What I ask you to
compare is with the result of gcc
gcc being the exact compiler use for compilation of the test program.

If these libraries are the same, then I will look at your test program,
otherwise I will not waste more time on this issue.
