Compile and run program without main() in C

Question

I\'m trying to compile and run following program without main() function in C. I have compiled my program using the following command.

Answer 1

In C, when functions/subroutines are called the stack is populated as (in the order):

1. The arguments,
2. Return address,
3. Local variables, --> top of the stack

main() being the start point, ELF structures the program in such a way that whatever instructions comes first would get pushed first, in this case printfs are.

Now, program is sort of truncated without return-address OR __end__ and infact it assumes that whatever is there on the stack at that(__end__) location is the return-address, but unfortunately its not and hence it crashes.
