I find it awfully hard to reliably trigger a semantic nest size
overflow. The best I have been able to come up with was
dak@lola:~$ tex
This is TeX, Version 3.141592 (Web2C 7.5.6)
**\def\x{\vbox\bgroup x\x}\x
! TeX capacity exceeded, sorry [semantic nest size=500].
<recently read> \bgroup
\x ->\vbox \bgroup
x\x
<*> \def\x{\vbox\bgroup x\x}\x
No pages of output.
Transcript written on texput.log.
But this only barely triggers, since 500 is less than 2*255, the
grouping level limit. And I can't at the moment think of a way to get
more than two semantic nests per grouping level.
Can anybody think of a semantic nest without grouping apart from
unrestricted hmode (which I use above)?
