Bug description
I get a "Bus error" when running a unit test on a doubly-linked
circular list (of length 2). I have 8 fields in a record which includes two left & right
pointers (not ref types).
I am running a PowerMac G5 2.5GHz (uname -a: Darwin ford.local 8.8.0
Darwin Kernel Version 8.8.0: Fri Sep 8 17:18:57 PDT 2006;
root:xnu-792.12.6.obj~1/RELEASE_PPC Power Macintosh powerpc) and
ocaml 3.09.3.
Interestingly, if I remove a field (such as the mark field), the test
case succeeds.
