I have checked the behavior of Free42 on Windows and Android. The behavior is similar: takes way longer if the domain is exactly 0,Pi. The problem appears only on the decimal version. The binary just works fine. On Windows the integration
ends up slowly but it ends. ...

I'll have to look into that.

Free42 in iOS 11 (iPhone), after few seconds (about 10-15) with acc. 1E-20 I get -5.731411E-34 (and not 0)

Hmmm. I guess it's probably not so much a bug as a difficult case. Error estimates get tricky when the exact result is zero. Still, something to look into.
