hi yannnick,

destructor of PContainer tries to free an object here that was already freed.

why are you on release libs again?

for the debug snapshots make sure (debian) that LD_LIBRARY_PATH or so 
contains /usr/lib/debug added.

ldconfig /usr/lib/debug should do it (?).

for own lib builds changing from release to debug do

make uninstall

make debug (pwlib, opal, ekiga)

-opal/pwlib installers will install only release libs.

-for debug libs install override with:

make install PTLIB_FILE=libpt_linux_x86_64_d.so
-------------------------------------------^ unstripped debug .so

make install OPAL_FILE=libopal_linux_x86_64_d.so
-----------------------------------------^ machine architecture suffix for amd64 e.g.


check with ls <prefix>/lib/<libopal*|libpt*> if install was ok, there may be no "r" so's 
around, even not in /usr/local/lib or they get dynamically linked instead.

happy testing.
