I reproduced this on my own Linux System (Ubuntu 18.04) using current
master.

I created

https://sourceforge.net/p/testlilyissues/issues/5651

I have also attached a back trace of the core that was dumped running
the above ly example.

Then I went through and compiled some earlier 2.19 builds and it seems
that, at least up to 2.19.12-1, this file did not core dump and I got a
successful PDF compile.

However I am not able to compile any builds between and including
2.19.13 and 2.19.37, and then 2.19.38-1 produces the same assertion.

Hope this helps.

James
