Since some weeks I have strange problems with MetaPost in MKIV (beta).
The
attached example should (and did in the past) output a central box
("Fakt")
surrounded by five boxes named "Dimension". However some of them (in that
particular example one) is drawn wrong: the box is on the right spot, but
the label seems to be at 0,0. It seems to happen whenever the boxes are
drawn from within a loop - at least all of my problems with boxes show
similar symptoms and only occur within loops.
Any ideas what goes wrong here?
Probably a metapost bug, I'll check.
There were actually two metapost bugs from that single example.
Next week's luatex beta will have a fix for both.
Bug 1:
show "45">"["; % 1.502 gives true, should be false
Bug 2:
pair a[]b;
a1b = (50,50);
pair a[]c;
show known a1b; % 1.502 gives false, should be true
Best wishes,
Taco
