programming error: cyclic dependency: calculation-in-progress encountered for Slur.control-points

[Federico Bruni]

Hi all

I'm testing 2.23.80 on my private sheets and I'm looking for errors... 
I don't know if this occurred with previous versions. Probably it did 
but I didn't notice it as I use a build system to compile multiple 
files and usually I don't look at the huge output (colored warnings and 
programming errors would help BTW).

What is this cyclic dependency? Any idea?
The file is copyrighted but I'm happy to send it privately to anyone 
interested in debugging it.
