Re: [Ekiga-devel-list] Real Issue is Opal::Call virtual table missing

[Lorin Melander <lwmelander gmail com>]

HI Eugene,

I observed the Virtual Table of Opal::Call is missing at second answer
or hungup.
First answer
(gdb) print *call
$1 = {_vptr.Call = 0xb7e7d660 <vtable for Opal::Call+256>
Ekiga answers successfully.

2nd answer
(gdb) print *call
$1 = {_vptr.Call = 0x33352020,
Ekiga crashs with pure virtual method.

The second answer or hungup will have pure virtual method crash since
the *call could not find Opal::Call.

I notice that the boost::bind or boost::signal is not really reliable
following the Opal::Call object.

Best Regards,
Lorin
