it seems, something is wrong with compiling gnokii in FreeBSD 4.6.2 or I'm 
missing
something, but the gdb session with latest cvs build follows ;)

It seems, compiler optimizes? line 98 in gsm-statemachine.c and emptydata 
variable
is not initialized. Compiling without -O2 does not help.

address@hidden:~# gcc -v
Using builtin specs.
gcc version 2.95.3 20010315 (release) [FreeBSD]

The same applies to gnokii (I debuged smsd, but when run, both crashes in the 
same place ;)
