Comment #48 on issue 2533 by address@hidden: Patch: line_count fixes
http://code.google.com/p/lilypond/issues/detail?id=2533

Segfaults in repeat-sign.ly.  Probably Keith tested without switching  
optimization off (try ./configure --disable-optimising).  It really is not  
a good idea to short-circuit our safety procedures without good reason.

Here is some traceback data:
