This doesn’t crash in current master.

Sorry, here comes the buggy example:

\version "2.19.83"

\relative c'{
\time 2/4
% This first line gives the error:
d16 d64-. ( d-. d-. d-. ) e16 e16:64 fis16 fis16:64 g16 g16:64 |
% Explicitly shortening the beam helps:
d16 [ d64-. ( d-. d-. d-. )] e16 e16:64 fis16 fis16:64 g16 g16:64 |
% Very similar pattern that doesn't trigger the bug:
d16 d16:64 e16 e16:64 fis16 fis16:64 g16 g16:64 |
}

Hi,

The following example illustrates a bug in 2.19.83 that's a regression against 2.18. Compiling with 2.19.83 gives

GNU LilyPond 2.19.83
Processing `bug.ly'
Parsing...

Preprocessing graphical objects...lilypond: /home/gub/NewGub/gub/target/linux-64/src/lilypond-git.sv.gnu.org--lilypond.git-stable-test/flower/include/interval.hh:227: T Interval_t<T>::center() const [with T = double]: Assertion `!is_empty ()' failed.
Abort (core dumped)

Uncommenting the first bar gives a file that can be processed and the second bar shows a workaround that works for the piece I'm typesetting. The example compiles without problems in 2.18.2, I don't have access to 2.21, so I don't know if the bug remains there.
