Usually a sign of buggy code more often than anything else. There are very
good memory debuggers that a programmer should use before looking further.

Are these uninitialized the first time through? If so, you can't simply 
"free" the pointers.

then it's a good time to learn the basics of C character string routines 
and memory allocation.
