Use gdb. We could probably point you to your problem but you need to learn how to use gdb.
the commands you need are:
Quote:
break main <- stop right when the program starts.
step <- enter this repeatedly until you get a segfault.
print [varname] to view contents of a variable
help <- gives you more things to use to navigate
help [command] gives specific help.
compile & debug with
Code:
gcc filename.c -Wall -g -o filename
gdb filename
gdb>  break main
r 
[boom! it segfaults gdb will give you the exact line in the file]

Have fun.
