Hi Clemens,

the crash is because the 'symbols' argument to 
'get_wspr_channel_symbols()' is null. I don't see how a program error 
could cause that to happen so I think there is a problem elsewhere. It 
may be a stack size problem. Try increasing the process stack size limit:

   ulimit -s
   ulimit -s unlimited
   ulimit -s

and see if that helps. Check that the limit actually changes by 
comparing the results of the first and last command above.
