Correction the the above post, although it's running now I seem to be
getting some segmentation faults, it does not happen all the time mind
you. It could be related, this backtrace is without debugging symbols.
If needed I can recompile to add a debug backtrace too.

Seems this bug is related to /usr/lib/libmysqlclient_r.so.15. Was using
5.0.32, which I upgraded to 5.0.51 and now mysql and mysqli can run
together again.

mysqlnd is yet to be released for production use... So for now, that
seems not to be the way.
I'll upgrade the mysql libs on a test machine after my vacation (after
august 5th, that is). I'll post my findings here.
Thanks for looking in to this!
Cheers,
Dirk

Which means that one will be better served with mysqlnd?

By the looks of the valgrind output, IMO, this is some bug in the mysql
lib. Try google for __lll_mutex_lock_wait and you get plenty of hits
pointing to discussion forums. Corrupted heap, -lpthread vs -pthread,
etc. among the possible problems..

Yes, and I was wrong... :)
In my opinion, bug#42625 went the wrong way (specially the last few
comments), so it would be clearer to start a new bugreport...
