It's a bug which is not OS X specific. Attached you'll find a patch
with the fix. I suspect that the reason is that lme4 uses direct calls
to C code of Matrix (why doesn't Matrix provide R-level interface for
this? I thought calling C code of another package is strongly
discouraged...), the interface changed and one of those calls was not
(CC to maintainers in case they didn't find out yet ;)).
