[Asterisk-Users] chan_h323 core dump on reload, works fine at startup

[Jeremy McNamara]

It only core's when u use the gatekeeper component, due to the way pwlib 
deals with memory allocation. This is going to take quite a lot of 
trying various different incantations to fix, unfortunately I cannot 
justify dedicating that kind time, at this point.

Sorry,
