But integrate(Y_1(x),x,r_0-r_1,X).expand()crashes Maxima (and Sage) :

This can be reproduced in Maxima. This works as expected:
But asking for integrate(Y_1(x),x,r_0-r_1,X);crashes Maxima with the same error messages...
This seems different from bugs already reported on definite integration.
FWIW, both giac and fricas give acceptable answers (different in their integration process : one uses arcsin, the other arctan, with similar geometric interpretation...).
Upstream: Not yet reported upstream; Will do shortly.
As the Sage-8.8 release milestone is pending, we should delete the sage-8.8 milestone for tickets that are not actively being worked on or that still require significant work to move forward. If you feel that this ticket should be included in the next Sage release at the soonest please set its milestone to the next release milestone (sage-8.9).
Inspired by this ask.sagemath.org question:
So far, so good :
