Ugh. The exact conditions to induce this bug are very difficult.

It is possible to come up with an example with somewhat fewer notes
and fewer measures, like this:

%%%%%%%% BEGIN %%%%%%%%%%%%

\version "2.7.38"

\new Score \with {
  proportionalNotationDuration = #(ly:make-moment 1 256)
} <<
  \new Staff {
     \set allowBeamBreak = ##t
     \time 2/8
     c'8[
     c'32 c'32 c'32 c'32
     c'8
     c'32 c'32 c'32 c'32
     c'8
     c'32 c'32 c'32 c'32]
  }
>>

%%%%%%% END %%%%%%%%%%%%%

... but cutting the example down even further usually causes the
problem to no longer manifest.
