--- Comment #15 from Jack Howarth <howarth at nitro dot med.uc.edu> 2011-02-01 15:11:51 UTC ---
DYLD_LIBRARY_PATH is unset when xplor is started. Also remember that your test
case in comment 9 is insufficient to reproduce the behavior of xplor-nih. The
code calling the unwinder should be placed in a shared library and then called
from a main program. I don't see anything in the following linkages which
should cause a problem.

As for DYLD_LIBRARY_PATH, changing...

Perhaps r163267 is fragile to certain combination of linker flags (like
-flat_namespace)?
