*** buffer overflow detected ***: [...]/bin/lilypond terminated

[Knut Petersen]

If lilypond master is spawned from a lualatex 1.0.4 process with 1023 open 
files it hits a hard limit:

   lilypond -E --pdf -O TeX-GS -daux-files=\#t -dgs-load-fonts=\#t tmplily.ly

then fails with

    >>tmplily.ly<< wird verarbeitet

The nofile soft limit is 2048, gcc (SUSE Linux) 7.2.1 20171020 [gcc-7-branch 
revision 253932] is used.

Part of the problem is that lualatex keeps all pdf files that are include via 
\includegraphics open, so reaching 1023 open files is possible.
xelatex behaves differently - it does not keep files included by 
\includegraphics open.
