[metapost] metapost crash

[Stephan Olbrich]

Hi,

I'm trying to make several pictures in a loop.
Basically it look like this:


for k = 1 upto 10
  beginfig(k-1)
    draw begingraph(13u, 4u);
        gdraw file[k];
    endgraph;
  endfig;
endfor

Without the loop it works for every file, but in the
loop metapost crashes (without any message). If the
data-files are shorter it crashes later, so I assume
metapost runs out of memory. I don't really understand
why, because after each figure it could forget all
about it.

Any ideas why this happens, or what I could do?

Stephan
