Re: Isolated example for : Variable used before given a value: prev-offset - msg#00076

[Phil Holmes]

It compiles fine on my system on both 2.12 and 2.13.41 - albeit with, to my 
eyes, strange but the same output on both.

Hello,

I finally traced where the problem is. I am sending the example.
What is strange is that it works with 2.12 (latest version) and not on the
lates dev version 2.13-41-1

Sorry it is not that concise, but it is still 2 measures long (the first
measure is for comparison)

Apparently what's wrong is the \override Rest #'Y-offset = #0 override in
the second measure (see comment in code). And moreover, if we change this
second measure into a simple 2/8 it works.

Here is the code. Hope this helps

Best regards
