Circular dependencies - Deadlock

[Michael Käppler]

Hi all,

I searched the bug tracker for the following issue but did not find 
anything...

Consider two files:

foo.ily:

\version "2.19.59"
\include "bar.ly"

bar.ly:

\version "2.19.59"
\include "foo.ily"

{ c4 d e f }

If you try to compile bar.ly the parsing process continues forever, 
apparently because Lily includes the two files in a circular manner 
(maybe reaching a memory limit at some point - did not try that)

Am I right to consider this a bug?

Regards,

Michael
