Its state is a mix of preinitialization and caching translations as it goes along, so inconsistent state indicates there's a fragile initialization somewhere. the py2/py3 switch has all kinds of small effects, so it could change the enumeration order of a set somewhere, so that the initialization happened to go right in py2 but now ends up going wrong in py3.
Concerning your hint of a bug: integrate(unit_step(x),x,-1,1) works just fine for me (it leaves the integral unevaluated). Without a piece of code that reliably reproduces the error you encounter it's virtually impossible to find what's wrong. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
