A problem with dynamic matrix in C

Question

I was playing with memory allocation in C and I really don't know what's wrong with code below. Segmentation fault occurs if I run it, but if I comment the print_matrix() function in main(), nothing wrong happens.

It's really confusing for me, but the print_matrix() seems to cause the problem.

Answer 1

Line 21 and 22 is overwriting the pointers line 19 stored. Plus, many more. This is updated to work.
