Thanks for the catch.  I fixed this by making the change you suggested in  
find_suboverlap_start(), and added your test as tests/issue133.c.  I  
noticed that the SEGV only seems to happen with a buffer size of 1 (2 also  
works, but the size we typically use, 1024, seems to prevent the SEGV from  
occurring).
