[XeTeX] xdvipdfmx says "** ERROR ** Capacity exceeded"

[Daniel Rubin]

Dear xetex list,

I've got a problem with xdvipdfmx trying to build a PDF from an xdvi
file compiled with xelatex.

The logfile is empty except for this:

<FONTMAP:cm-dvipdfm-fix.map><FONTMAP:dvipdfm.map><FONTMAP:cid-x.map>
** WARNING ** DVI need stack depth of 291,
** WARNING ** but DVI_STACK_DEPTH_MAX is 256.
** ERROR ** Capacity exceeded.

I have no clue as to what's causing this.  It happens with about 1 out
of 1000 source files I'm creating.  I'd be glad to get some help to
pinpoint this.

What stack is this DVI stack?

What may be causing it to become so deep? E. g. can I do something to my
latex-source, embedded images, fonts or whatever to make this go away?

I'm creating through an automated process and I'm afraid simply going to
the source and increasing the limit will only make this problem go away
for a little longer rather than forever.

I'd be grateful for any ideas.

Thanks in advance
----Daniel
