have you got a misdn trace for this situation? Probably the call has been hungup at the same time when you call misdn_set_opt. I believe either "ch" or "ch->bc" are NULL.

could you enter the following in gdb:

p ch
p ch->bc

(gdb) p ch
$1 = <value optimized out>
(gdb) p ch->bc
Cannot access memory at address 0x12ac
(gdb)

dwagner:  You're going to need to recompile with DONT_OPTIMIZE in order for us to be able to help you.

because of major problems with version 1.4 we decided to switch to version 1.2. sorry
