Maybe that's a language issue on my end. But afaict, the UBSAN isn't a static
analyzer but a runtime analyzer. So, if you see that UBSAN output it means
that that part of the code *was* reached with a NaN value. I.e., there is no
check in Octave that would have caught non-finite values in this case.
