Re: Crossref in bibtex

[<context@joshuamoerman.nl>]

Dear Alan,

Thank you very much fox fixing the issue so quickly! The patch you have sent
me works on my machine as well :-).

I was playing around with bibliography a bit more, and I noticed that when
you make a crossref-loop (two entries pointing to eachother, or a single
entry pointing to itself), the lua interpreter will crash with
"publ-dat.lua:540: loop in gettable stack". Now, this is a bit of a silly
case of course ;-).

Kind regards,
Joshua

crossref is implemented and works, but failed as shown above, when the
crossref points to a "future" entry, that is one not already processed
(inverting the order of the two entries above will show the desired
behavior).

This is not good: the order should not matter, and Hans has fixed this, to
appear in the "next beta". Thank you Joshua for uncovering this.

Alan
