Minisip Trunk. Problems compiling an 100% use of cpu

[Carlos Oliva]

Hi the list!

Compiling the last code in the trunk I have some errors in libminisip:

/home/carlos/minisip2/minisip/trunk/libminisip/source/subsystem_media/MediaHandler.cxx:
In member function 'MRef<Session*>
MediaHandler::createSession(MRef<SipIdentity*>, std::string)':

/home/carlos/minisip2/minisip/trunk/libminisip/source/subsystem_media/MediaHandler.cxx:133:
error: cannot allocate an object of abstract type 'CallRecorder'

/home/carlos/minisip2/minisip/trunk/libminisip/include/libminisip/media/CallRecorder.h:60:
note:   because the following virtual functions are pure within
'CallRecorder':

/home/carlos/minisip2/minisip/trunk/libminisip/include/libminisip/media/soundcard/SoundRecorderCallback.h:52:
note:         virtual void
SoundRecorderCallback::srcb_handleSound(void*, int, void*)

Using ubuntu and gcc 4.1.2

To compile it I use a very ugly trick, I comment the lines of the
fault ,lines from 141 to 146 of
libminisip/source/subsystem_media/MediaHandler.cxx (I submit the
little diff attached)

After compiling it, I have the problem of complete use of CPU by
minisip. After 1 or 2 minutes (I have no audio, but I think is for my
changes in mediahandler.cxx) the cpu goes to 100%.

Using profiling utilities (qprof) I get this:

It seems that one simbol of libminisip is eating the cpu... (pentium 4 2Ghz)
Entering in the library I only see: 00093098 T _Z4dotpPfS_
If somebody interested I will send him/her the binary of the library
(I think 2182655 bytes is too heavy for the list)

 What do you think about?

Thanks for advance:
