Using asprintf without memory leaks

[Ian Pilcher]

asprintf(3) says:

   When successful, these functions return the number of bytes printed,
   just like sprintf(3).  If memory allocation wasn't possible, or some
   other error occurs, these functions will return -1, and the contents
   of strp is undefined.

If -1 is returned, can I at least assume that any memory that was
allocated has been freed?  If not, it's hard to see how asprintf can
be used without risking memory leaks.
