make sure you have coredumps turned on.. (ie. maybe in your defaults shell
rc's you have the line "limit coredumpsize 0", find it and turn it off, or
type unlimit coredumpsize

i like to use the -g -Wall options..... 

debug info is in by default... you turn it off with the -s option .


> gdb bin/circle

gdb> run 4000

and when it coredumps do a    l (for line), and a bt  (backtrace)
