[tex-live] mpost segfault

[Thomas Esser]

Dear Hans,

Sorry, that can't work.

metafun.mem is created with -progname=mpost, so it will use the array
sizes of mpost.  "mpost --mem=metafun" (which reads metafun.mem) uses
the array sizes of metafun. You have to use
  mpost --mem=metafun --progname=mpost

Demo:

    $ mpost --mem=metafun -progname=mpost mandala.mp
    This is MetaPost, Version 0.901 (Web2C 7.5.5)
    (mandala.mp [1]
    metafun 2005-10-26 18:24
     )
    1 output file written: mandala.1
    Transcript written on mandala.log.

    $ mpost --mem=metafun  mandala.mp
    This is MetaPost, Version 0.901 (Web2C 7.5.5)
    (mandala.mpSegmentation fault

While we are at this: the lines

  main_memory.metafun     = 2500000
  pool_size.metafun       = 1000000

in texmf.cnf contradict the implementation of fmtutil (which makes sure,
that the array sizes of mpost are used for metafun.mem creation and not
the ones of metafun).

It would be a similar nonsense to have a
  main_memory.cont-en
setting which makes no sense (texexec and fmtutil both pass
-progname=context when using cont-en).

That, you can change into
  $mpbin = 'mpost' ;
