Debug using LLDB
gcc filename.c -g
lldb a.out
b main
run
gui
pressing s each time will progress the program 1 step forward.
Find Segmentation fault using LLDB
gcc filename.c
lldb ./a.out
run
This will likely show assembly code, but it will show the name of the function which is causing segmentation fault. Files can be compiled mannually to see the source code in C that is causing segmentation fault. When I figure that out I will post it.
