thank you for looking at this.
I am running Emacs 21.4.1 Nothing bleeding edge here.
The help for split-string looks reasonable (compiled Lisp comes from "subr" ....) (complete output attached)
split-string is a compiled Lisp function in `subr'.
(split-string STRING &optional SEPARATORS)
Splits STRING into substrings where there are matches for SEPARATORS.
Each match for SEPARATORS is a splitting point.
The substrings between the splitting points are made into a list
which is returned.
If SEPARATORS is absent, it defaults to "[ \f\t\n\r\v]+".
If there is match for SEPARATORS at the beginning of STRING, we do not
include a null substring for that. Likewise, if there is a match
at the end of STRING, we don't include a null substring for that.
Modifies the match data; use `save-match-data' if necessary.
I think that explains it: split-string takes one mandatory and two
optional arguments (separator regexp and an omit-nulls boolean) in
emacs-22/23; but only *one* optional argument in emacs-21 (the separator
arg). The org latex-exporting code calls it with two optional arguments
and that makes the emacs-21 implementation of split-string blow up.
I just did an experiment: in my emacs-23, I called split-string
with one mandatory and *three* more arguments:
baz" "\n" t t)
and I got output which looks very similar to what you are getting.
So I think it's an incompatibility with emacs-21. Try the following
patch for now and let us know whether it resolves your problem:
