I doubt it's caused by any custom-engraver.
At least on my machine this code:

\paper {
  systems-per-page = #5
}

music = \absolute {
    \repeat unfold 2000 {
      d'8 f' a' g'  d' f' b' d' d'8 f' a' g'  d' f' b' d' \break
    }
}

\new Staff { \music }

already fails with:
[...]
Preprocessing graphical objects...terminate called after throwing an
instance of 'std::bad_alloc'
  what():  St9bad_alloc
Aborted (core dumped)

on Ubuntu 64-bit 18.04 for any tested version (2.18.2 up to current master)

Cheers,
