 0.739... is a fixpoint of the cos() function, so if
 everything works well, the variable doesn't change
 much. The "nan" result shows that the calculation
 of the cos() failed. In this case it is due to an
 overflow of the i387 FP stack.

 No output is good output - the function iterates
 as it should.

 Hmm - this could mean that qemu's i387 model does not
 signal the stack overflow. That's likely a bug.
