Saxon

Reported by Norm Walsh on saxon-help mailing list:

Hi,

I hope this is useful. Apologies, I don’t have time to coax out a

smaller test case. It’s a small DocBook document. Works fine with

Saxon 9.6 and 9.8, but blows up with 9.7.0-11 and 9.7.0-21.

If you want to run it, I believe the following recipe will work,

though it carries a bit of baggage along with it.

1. Clone https://github.com/docbook/xslt20-stylesheets/

2. Run:

gradle -PsaxonVersion=9.7.0-21 -PxmlCalabashVersion=1.1.16-97 \

     --stacktrace relNotes

It’ll chug on for a bit, download half the internet, compile some

stuff, and then go bang.

On and on and on so many times that it blows out not just the stack,

but also the size limit for messages to this list!
