Bug? Solve in CAS causes warm start

[Nigel (UK)]

On my Prime (latest firmware) entering (for example)

Code:

solve(x^3=1.2e-15,x)

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?
