Description
CI run produced an FPE while running test.Plane.FlyEachFrame. I've never seen this before.
The PR in question is going absolutely nowhere near the relevant code (should actually be a no-compiler-output change in SITL?). #28966
Link to output is below, also excerpted below.
Seems to be something wrong with the maths in limit_accel_xy - we're taking the square root of a negative number; something wrong with taking the cross product, perhaps?! Thankfully the output below contains values for all of the variables required...
