  1. The change of sequences from reals to integers has created a number
of problems. I already mentioned this earlier on the list but here is
another example:
contour(1:10,1:10,z)
where z is an appropriate matrix, does not work. After searching quite
a while, I discovered in the C code that contour checks for reals and
does not allow integers. Someone is going to have through all the C
code and change checks for reals to numeric anywhere where sequences
might be used.
  2. I am still getting systematic crashes when nlm is used heavily
(since at least last May when I first told it on the list, so this is
not new to the latest versions).  When nlm is working on a big problem
intensively for say 5-10 minutes (Pentium 133 with Linux Red Hat 4.1),
the X server often crashes. If I try to paste something into emacs,
emacs alone will often crash, sometimes when that is the only thing I
am doing, but more often when I adjust a window or click in a
slider. I can usually, but not always, restart X but it is bound to
happen again so I usually need to reboot. Sometimes it freezes the
whole computer and I have to shut it off. It seems to occur mostly (if
not always) when (log) gamma is being used in the likelihood function
being optimized. But it is not reproducible so I cannot give an
example.
