I have trimmed the strace output, but I can provide full output if
necessary.
It works in with PHP 4.3.10-15 on debian stable:

With php5.1-200601021330:
The link /home/user/C gets translated to /home/user/x/A and what should
be accesses to /home/user/C are accesses to /home/user/A as seen in the
second last line of the following strace.

You can strace the script and see what files are actually being
accessed.

I tested the "lastest" version (php5.1-200601021330) on debian stable
and it failed. Over the holidays I tried 5.1.1 with debian testing and
it passed.
A summary of results:
4.3.10 - debian stable - pass
5.1.0b3 - debian stable - fail
5.1.0 - debian stable - fail
5.1.1 - debian stable - fail
5.1.1 - debian testing - pass
php5.1-200601021330 - debian stable - fail
5.1.2RC2-dev - SUSE Linux 10 x86_64 - pass
Common to all failures is Debian stable. Do you have any suggestions
on how to approach finding what is causing the fault?
