I see. I didn't think of it, but you are right.

Umm, at least apr 1.6.3 does not seem to use DEEPBIND, that might fix the
issue, yes. A simple "grep DEEP * -R" gives nothing.

That's what I did, but instead replacing RTLD_GLOBAL with RTLD_LOCAL, and it
seemed to work. It seems to work as well with RTLD_DEEPBIND.
