Fire up gdb on the core dump (or run it under gdb until you get the fault) and find the line that the segmentation fault is happening on. Find the pointer that causes the error. Then all you have to do is to work out why it isn’t a valid pointer.

There are four common mistakes that lead to segmentation faults: dereferencing NULL, dereferencing an uninitialized pointer, dereferencing a pointer that has been freed (or deleted, in C++) or that has gone out of scope (in the case of arrays declared in functions), and writing off the end of an array.
