Bug#159733: tetex-bin: MetaPost `label' primitive produces faulty postscript.
Package: tetex-bin
Version: 1.0.7+20011202-7
Severity: important
Using the `label' primitive in a MetaPost file makes ghostscript barf.
MetaPost files without the label primitive works fine.
To illustrate the problem, I have made two files: s.mp and t.mp, where
the first contains no labels, thus cause no trouble for gs. I include
the test files, output from MetaPost, the postscript file produced by
MetaPost, and the output from gs.
$ cat s.mp
beginfig(1);
z0=(0,0);
z1=(1in,3in);
z2=(2in,4in);
drawarrow z0..z1..z2;
endfig;
end
$ mpost s.mp
This is MetaPost, Version 0.641 (Web2C 7.3.7)
(s.mp [1] )
1 output file written: s.1
Transcript written on s.log.
$ cat s.1

As can be seen, the above caused no trouble for gs. The below, however,
does. I have typed in other examples too, directly from the MetaPost
manual, but all the ones with labels in them fail. Does anyone else
experience this? Is there something fundamentally wrong with my system,
or should I file a bug report?
$ cat t.mp
beginfig(1);
z0=(2in,4in);
label("hello world", z0);
endfig;
end
$ mpost t.mp
