On my Prime (latest firmware) entering (for example) in the CAS screen causes a warm start on the physical calculator, and a crash on the emulator. fsolve behaves in the same way.

The crash doesn't happen if the right-hand side is greater than 1e-12, or if x^3 is replaced by x^2.

Can anyone reproduce this? If so, is it a known bug?

Yes, I can reproduce the warm start on the physical calculator.

HP 50g returns 1.06265856918E-5, no problems.

A workaround: enter (note the 3.0 in the power) and the correct solution is given with no crash. This works with both solve and fsolve. Still a bug, though, I'd say!

I have modified giac for this case, it was returning an error (but unfortunately not on the Prime because of the OS).
