c++ with pthread?

Actually, I've run into a decision forcing event with commoncpp. It segfaults 
one of it's own very simple test code (thread2.cpp) :
http://www.gnu.org/software/commoncpp/docs/refman/html/thread2_8cpp-example.html

Either it's me, FreeBSD or the actual librairie that cause the segfault. I've 
even 'sent-pr' to update the port to the last version and it causes the same 
segfault.

gdb gives:

0x280d4c95 in ost::Thread::close () from /usr/local/lib/libccgnu2-1.3.so.1

from thread2.cpp compile like so:
gcc -I/usr/local/include/cc++2 -D_THREAD_SAFE -D_GNU_SOURCE 
-I/usr/local/include -L/usr/local/lib -lccext2 -lccgnu2 -L/usr/local/lib 
-lxml2 -lz -L/usr/local/lib -liconv -lm -lz -pthread thread2.cpp

Since the actual fault is in libccgnu2, I've submitted a bug report on 
sourceforge.

Sadly enough, this situation has cause me to stay with pthread so far.

About  ptmalloc2, is the reason it wasn't implemented a compatibility issue? 
Licensing maybe? Technical?

Nicolas.
