[asterisk-users] Segfault on unload of chan_h323 in asterisk-1.4.25

[Alex Villací­s Lasso]

When the support for h323plus was announced for Asterisk 1.4.25, I tried 
to build this support in Asterisk. For this, I checked out the h323plus 
CVS from SourceForge, which reported version 1.20.beta5, and also the 
ptlib-2.4.2 source RPM from Fedora 10. I finally managed to build a 
chan_h323 for Asterisk 1.4.25, which apparently loads correctly, but now 
I see that I get a segfault whenever I issue the command "module unload 
chan_h323", or "stop gracefully". I have yet to file a bug on either 
Asterisk or h323plus because I believe this to be my own error in 
configuration, rather than an intrinsic bug in chan_h323. Does anyone 
else have chan_h323 running with h323plus? If so, how did you compile 
your support? Have you experienced the segfault on shutdown?
