Thanks for debugging. I have no experience in debugging low level stuff,
you showed me a way to go.

It was really a Xfree problem, I reported to the maintainer about the
issue. He knows about the problem with static libs and expects a fix
from upstream soon.

_mixer_exit belongs to esd plugin - it was affected by the same problem.
Having disabled DGA, DGA2, VIDMODE and esddigi, I can not detect any
non-PIC code in the library or in the plugins. Thanks for the help! It
is not a nice solution to disable all drivers, but better than having
problems with them on the other hand.

It works! No non-PIC code any longer. On the weekend, I received a new
bug report, complaining about linking problems with non-PIC code. In
fact, gcc on HP-PA refuses to link PIC and non-PIC objects together.

Now, there is still one problem:
misscompilation using gcc-3.0. Everything seems to compile fine (except
of tonns of error messages), but the created binaries are segfaulting
during the loading of the new library.

Tonight or tomorrow, I will try the same in another environment.
Something weird is going wrong, I have a strange feeling with this
problem.

Gruss/Regards,
Eduard.
