Lilypond crashes while drawing systems

[Lukas-Fabian Moser]

Folks,

I seem to have managed to create a Lilypond file that crashes my system 
(Linux Mint 64-Bit with kernel 4.4.0-98-generic) so hard that I have to 
shut it down using the power button. Even a bash script in background 
that kills the Lilypond process every few seconds cannot rescue 
reliably. :-( The system hangs while "Drawing systems" ("Systeme 
erstellen" on my pc).

Version is pre-compiled 2.19.80 64 bit.

So I'm sorry that the following example is not really minimal - it's not 
so easy to reduce further if you have to reboot after every other 
compilation.

In the original version, I had "tonart = f" (hence no transposition) 
which caused no problems. "tonart = fis" also works; "tonart = d" crashes.

  }
