As yesterday (on R-devel, with Kurt Suebert who had problems on a Dec Alpha):
This must be a bug in the handling of IEEE-Arithmetic,
i.e. +/- Inf and NaN
[to people not running "make check", it always shows first in the graphics!]
In your toplevel directory,
will most probably show how the IEEE-Arithmetic is broken.
(and please let us know how..).
