Re: Segmentation Fault in aprsd - SOLVED

["Roger Bille" <roger.bille@telia.com>]

 I have found the problem after recompiled the source with debug and using
breakpoints and stepping through the program with gdb.

 As expected my own fault. I had by misstake deleted the aprspath entry in
aprsd.conf. This caused the following call in sockets.cpp to fail:

    if ((tx_dest_len = ax25_aton(destcall, &tx_dest)) == -1) {
        cerr << "unable to convert callsign '" << destcall << "'" << endl;
        return 1;
    }

 Because the destcall was NULL.

 Regards
 Roger
