I've got segmentation faults in free_general_string and free_octet_string. 
I have used dmalloc and gdb to debug the problem. The "ptr = NULL" style
assignments in my patch made the segfaults go away, and the tests for
malloc'ing 0 bytes and free'ing NULL made dmalloc to shut up. So these
tests may not be neccessary, but resetting pointers to NULL after they'd
been freed is neccessary.
