OK. The problem already is in 'next' and we want to make sure it won't graduate to 'master' for the next release as-is.

I'd try the former first and will fall back on the latter, then. > Note that, even though commit a0731250 originates from a branch called > "hn/XXX" and has me as Author, the BUG() call causing the crash was > actually introduced by AEvar when he reworked the series. Yup, I see his Sob after yours and it is quite understandable if a new bug was introduced by his changes. It also would be understandable if his change was only to add a call to BUG() in order to assert that the original patch used myerr consistently, and it uncovered a bug in the original version he took from you. I do not care too much about how exactly the bug was introduced and uncovered---it matters more that the end result has one fewer bug thanks to the team effort.
