Testcase for RTLD_DEEPBIND unrealted to xine-lib.

Description of problem:
Filing here a Bug originally reported by Gregory Hosler.
xine-lib can crash in pulseaudio due to its (upstream fixed) Bug
But this Bug would not occur if xine-lib would not use RTLD_DEEPBIND in its patch `xine-lib-1.1.1-deepbind-939.patch' (cannot find any Bug number 939).
While I did not try xine-lib myself without this patch there are given no reasons in the .spec file for it.  Could be this patch removed?

This Bug occurs as RTLD_DEEPBIND makes the `environ' variable NULL.  Without RTLD_DEEPBIND such unusual (despite valid) state would not occur.

Version-Release number of selected component (if applicable):
xine-lib-1.1.16-1.1 (src)

Attaching a bit unrelated testcase (deepbind-environ) showing `environ' gets cleared due to RTLD_DEEPBIND.

I'm unfamiliar with the history too, but this seems to be it:
Comment 2 Kevin Kofler 2009-01-18 15:41:30 EST
Looks like the right fix there would be to get xine-lib-extras-freeworld to also use the system libfaad, if this isn't already done. Then we can get rid of that hack.
Comment 3 Rex Dieter 2009-01-18 16:07:09 EST
Yup, beat me to it.

Just committed changes doing just that (for rawhide/f11 anyway).  Provided the builds complete and nothing blows up, we'll consider doing so for other branches as well.

Nice it found a library duplicity, thanks.
