Well, more than 8000 lines of code is not exactly a good bug-report ;)
Let's reduce it to something shorter:

\version "2.25.19"
{
  \repeat unfold 5 {
    \time 2/8
    c'32[ r4 c'8 %]
  }
}

This gives a segfault in 2.25.19 on my machine, Ubuntu 24.04 and but
no segfault with 2.25.16.
Ofcourse there are a plethora of warnings, one of them pointing
exactly to the not terminated beam. Which is exactly the problem with
the last beam in your number.1.pitches-vl-voice.

And yes please file a bug report with the minimal: Although LilyPond
warns correctly about the problem, it should never segfault.

P.S.
I never look in such huge files more than once in a year!
