Thank you, Fabian (and Reinhold and Ben).
I think the version of Matrix and lme4 do not matter here,
really, but rather the compilers and libraries used to build
*and* run R.
Notably I have small suspicion that the case which show the
buggy behavior are linked to an optimized version of BLAS and
LAPACK, and these might be the culprit.
My (self-compiled) versions of R always use the R-builtin
non-optimized BLAS+LAPACK, so that would fit the picture that I
never see the problem.
Also, AFAIK, the Mac versions *do* use optimized libraries, and
Ubuntu often does too (because Debian does).
