Comment #3 on issue 1723 by address@hidden: beam fails to extend over
rest, intermittently
http://code.google.com/p/lilypond/issues/detail?id=1723
This occurs intermittently in several recent versions. With one version I
saw the bug when running Lilypond from the command line, but not when
spawning it from vi, so it could be uninitialized memory, or more likely
the engraving depends on an order of objects in some array or list, and
that order depends on details of how memory is allocated.
It is hard to be sure, but I think the minimum recipe is an automatic beam
from-rest-to-rest across a bar line:
{ \time 1/4 r8[ g' a' r] } #(ly:set-option 'delete-intermediate-files #f )
The postscript files for buggy- versus good-output purposefully draw beams
of the wrong- or correct length -- no zero-width beams or anything like
that.
Correction to the workaround: the *Stem*, not the Beam, gets the override.
\override Stem #'stemlet-length = #0.1 % or anything non-zero
