A quick follow up to this one.  The bug does NOT occur if I substitute
eqnarray for eqnarray*.  I believe that this means that the constant
org-latex-entities in org-latex.el needs to be modified to admit the
starred (unnumbered) variants of the latex math operators.

Unfortunately, my simple-minded attempt to butcher in stars has run
aground on the shoals of my ignorance of the combination of emacs-lisp
string escapes, and emacs regexpressions.  Simply adding

"\\begin{eqnarray*}"

to that list won't work, and even

"\\begin{eqnarray\\*}"

doesn't seem to do the right thing.  if anyone can put me on the right
track, I'll try to provide a patch.

Thanks!
