you malloc() a limited buffer using strcat(), but if the string is longer than u allocated memory for fname, the buffer will not be big enough. use strncat, and calculate the remaining space for the strncat() appropriately every time .
u will not get any problem after this.always use strncat ,it solves memory problems.
