Can you please send me a backtrace made with gdb instead of the one you sent
me? You should be able to get one by running

$ gdb --args gst123 -a alsa=66ch12 http://...

I've also added the command line option

$ gst123 --full-version

in the git version of gst123, having the output of this running on your machine
would also be helpful (in case your crash can only be reproduced with certain
library versions).

If you compile from git, you need to use

$ ./autogen.sh --enable-debug

to get debugging symbols (without them, the backtrace will not be useful).

Finally, you can try if your crash can be reproduced with the

$ gst123 -a none

option that I added recently, this should be easier (for instance if I want to
reproduce the crash here) than getting your ALSA setup working on another
machine.
