Subject:  Segfault in chan cpool_release_pool

Hi,

I am currently receiving a segfault with PJSIP SVN 5359 and unable to compile the latest SVN version due to the following errors:

trunk_REV5374/third_party/lib

/usr/src/pjproject-trunk_REV5374/pjmedia/lib/libpjmedia.so: undefined reference to `pjmedia_video_format_mgr_instance'

/usr/src/pjproject-trunk_REV5374/pjmedia/lib/libpjmedia.so: undefined reference to `pjmedia_format_get_video_format_detail'

/usr/src/pjproject-trunk_REV5374/pjmedia/lib/libpjmedia.so: undefined reference to `pjmedia_get_video_format_info'

collect2: error: ld returned 1 exit status

make[2]: *** [../bin/pjmedia-test-x86_64-unknown-linux-gnu] Error 1

make[2]: Leaving directory `/usr/src/pjproject-trunk_REV5374/pjmedia/build'

make[1]: *** [pjmedia-test-x86_64-unknown-linux-gnu] Error 2

make[1]: Leaving directory `/usr/src/pjproject-trunk_REV5374/pjmedia/build'

make: *** [all] Error 1

Can you please suggest a fix for the above?
