Comment(by zimmerma):

 Francois, I explain in comment [comment:18] that the semantics of {{{t ==
 s}}} is special for
 intervals. If {{{t=[a,b]}}} and {{{s=[c,d]}}}, it requires that {{{x==y}}}
 for any {{{a <= x <= b}}} and {{{c <= y <= d}}}, which obviously requires
 {{{a=b=c=d}}}.

 The modified tests did work before because they had {{{a=b=c=d}}}, which
 is no longer the case due
 to change of semantics of MPFI.

 Paul
