Some integrals with problematic evaluation

Makes sense. Please note that we've done everything possible to ensure that the emulator behaves identical to the device in every way possible. There are extremely rarely any differences in behavior, and these are almost exclusively hardware related things (difference in available memory, etc) and not differences in the software or behavior.

Nope. I always like to see qualified people trying to poke holes in the software. Without pushing, it is pretty hard to improve.

Could you elaborate on what you mean here a bit more? Basically, we track the xcas source directly to the extent possible so any changes and improvements made end up on Prime.
