If "newtext" is a char* (as I suspect it is), you
are just allocating as much memory as the size of
the pointer, not as much memory as the size of
the string that it is pointing to. You probably
want to use "StrLen(newtext)+1". The +1 is important
because StrLen() will give you the length of the
string, but will not account for the NUL character
which terminates the string.
