(Taco, thanks for all the infos. Now, just trying to understand).
Why the bug manifest itself in this particular tex file? I mean: I have
made other pieces, both with far less either with far more included pdfs
and everything was ok.
What's special in the bug-raiser tex we discussed about?
For every pdf you include, about 80 bytes is added to an internal
string. There is a macro that checks the length of this string, and
it sets a special "there are included pdfs" flag when the strings
length is larger than zero. However, the primitive metapost operation
to get the length of a string is rather stupid, it wraps without ever
checking anything. Just run this bit of metapost code and watch the
terminal output:
string s;
s := "";
forever:
s := s & " ";
message decimal length s;
endfor;
end.
(you'll have to kill the process manually)
So, my patch checks for 'not zero', which has a far smaller
chance of being incorrect. Not completely nil, unfortunately.
'length' can actually wrap back to being zero, I'll have to
fix that in metapost itself.
Cheers,
Taco
