[Doxygen-users] infinite loop from Doxygen-generated .tex

[Georg-Johann L. <av...@gj...>]

Hi, I am having considerable problems with Doxygen v1.9.1

In one of the (many) .dox files, there is this table an the
end of this mail.  It generates HTML okay, but the PDF header
is broken.

But the very problem is that somehow, this generates tex code
that will enter an infinite loop in a later table, and then
the PDF generation aborts.

This looks like a genuine Doxygen issue in some of its
LaTeX environments, and perhaps the code below is enough
to reproduce the issue.  I cross-checked the col/row counts
several times and cannot find a problem in the source.

Regards,

Johann
