Hi,

I still encounter crashes seemingly caused by libpt with Ekiga.

Here is the backtrace I get when Ekiga crashes after the program has
ran for a while:


Program received signal SIGSEGV, Segmentation fault.

And the backtrace I get when the program crashes just after it has
started:


Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x7fffd40d3700 (LWP 30781)]
0x00007ffff3e61c0f in PStringOptions::SetAt(PCaselessString const&, PString const&) () from /usr/lib/libopal.so.3.10.10

.
. (Same as before after that, just different frame numbers.)
.


Looking at the disassembly, the crash seems to happen on the call to
method MakeUnique() in the file include/ptlib/pstring.h at line 2867.

Hope this helps.

Cheers,
