Okay. I did this.
Using my other email as an example.
#0 0x480f42a6 in strcpy ()
#1 0x8067be0 in _hostname ()
#2 0x8051574 in main (argc=1, argv=0xbfbe5564)
#3 0x8049f9d in ___start ()
#0 0x482032a6 in strcpy ()
#1 0x805a6a0 in _hostname ()
#2 0x804da2c in main (argc=2, argv=0xbfbe556c) at main.c:356
#3 0x804a2e5 in ___start ()
But how can I easily find line "356" with all the #ifdef's and macros?
(Is there some tool for that?)
After testing further, it appears that the bad strcpy is really line 2434
in commands.c. I wonder why the backtrace says the other one.
Anyone have some good pointers to easy-to-understand documentation for
