Thanks! So, probably it is unrelated with the ticket I mentioned.
Also note that the computation time does not increase monotonely:

Harald, thank you for reminding us of this post.
Raphael,
Actually I started an answer a while ago, but thought it wouldn't be
helpful and therefore didn't post it.

It is a bug in the warning message indeed, in line 820.

Is there proper way to handle this?

Hi,
How to simplify an expression if you have some known relations
(equalities)? Example:
relation: 0 = a*x1^2 + b*x2^2
expression = (a*x1^2 + b*x2^2)*y1+b*y2^3
Are all your relations polynomial? Then the standard solution is

Dear All,
during development of a package, I changed the layout. When I started,

needed).
Problem: I saved some data in the old layout, and now I would like to
