Question: Error, (in type/complex) too many levels of recursion when adding 'assumingusesAssume'=true

Question:Error, (in type/complex) too many levels of recursion when adding 'assumingusesAssume'=true

This could be unrelated to V 26 of support tools and it could be a bug that existed in Maple before.

But no time for me to check now. Thought to ask about it before I forget.

When adding Physics:-Setup('assumingusesAssume'=true):  Maple generated internal error that can not be cought.

This is using latest V 26 of support tools

Error, (in type/complex) too many levels of recursion
