> Zdenek are you going to apply the patch, it has been approved?

the patch was approved, but after thinking about it more, I noted that
it works by pure luck only, and that the fix for find_base_value
would need to be more complicated.

However in the meantime the patch to prevent ivopts from producing the
type of expressions that caused the problem was commited, so the PR
should no longer reproduce.
