[XeTeX] xetex crash: interaction between interchar and linebreaklocale mechanisms

[Andrew Goldstone]

Thanks--it turns out that xelatex still segfaults if I attempt to combine
ucharclasses and \XeTeXinterwordspaceshaping=2 in a longer document. I do
think this is a bona fide xetex bug but don't have the knowledge of the
xetex source to trace it further.

As for lualatex it seemed to have more trouble than xelatex with the
complex ligatures in Burmese. The lineation issues are a lower priority for
my colleague than simply being able to typeset his mixed-script text, so
I'll help him to a workaround with xetex, if no other suggestions for fixes
are forthcoming.

All best,
Andrew
