Guess you forgot to try gdb:

Code:

gcc -W -Wall -Wextra -Werror -o mycode -g mycode.c
gdb mycode
run
backtrace

command 'backtrace' should come after SIGSEGV

Of course it won't help you if you keep compiling without option -g (I suggested it for a reason, not only because I am paid per characters)
