Malloc call crashing, but works elsewhere

Question

I wonder if anyone might have any insight on this...

My program is crashing on this call:

void subtract(data* array,data* inverse,int a, int b, int q         


        

Answer 1

You all are right, but anyhow I wonder why this crashes.

I wonder because the size of data (as defined above) is expected to be less or equal to the size of data*.
