A similar crash has been reported on -user-fr, which I was able to trim down to
the minimal example below (commenting any line solves the bug). Interestingly
though, this one’s reproducible even on GNU/Linux. (Whereas the previous
snippets in this ticket do not.)
~~~
\version "2.19.80"
% 2.18.2 doesn’t crash, whilst 2.21.0 still does.
\header { title = "foo bar" }
{
\pageBreak
c'1 \break
c' \break
\repeat unfold 4 c'
}
~~~
Here’s the log on GNU/Linux:
~~~
page-breaking.cc:1052: void Page_breaking::line_divisions_rec(vsize, const
Line_division&, const Line_division&, Page_breaking::Line_division*): Assertion
`my_index == 0' failed.
Aborted (core dumped)
~~~
See also the attached Windows screenshot, which looks a lot like what had
previously been reported.

Note: According to Phil H's own tests: "This started in 2.19.21. 2.19.20 is
OK."
