[R-sig-ME] current r-forge version fails R CMD check ... ?

[Ben Bolker]

  When I use the latest r-forge version of lme4
(  0.999375-32 ) it seems to fail R CMD check on a tiny
numerical mismatch of two objects that are supposed
(??) to be identical (I also
get a mangled CHOLMOD error message, but I suspect that
comes from somewhere within Matrix ...)

  can anyone confirm? any ideas for a fix?

  The offending mismatch between ranef(m2) and ranef(m3)
is very small ...

> ranef(m2)
$ff
  (Intercept)          x2
1  -0.8896154  0.06947426
2   1.9253111 -0.15035662
3  -0.1315062  0.01026994
4   0.2420718 -0.01890453

> ranef(m3)
$ff
  (Intercept)          x2
1  -0.8896130  0.06947407
2   1.9253069 -0.15035628
3  -0.1315054  0.01026988
4   0.2420710 -0.01890446

  (this doesn't affect anything I'm doing directly, but
I want to build some Windows binaries of a hacked version
using the CRAN win-builder, and to do that I think it
needs to pass R CMD check ... for now I am going to
try commenting out the offending test, but that seems
like a bad idea in general ...)
