Don't agree here: the stability issues were already fixed in the
commit I made. Simplification of code I agree with. But whatever, I
can't and won't waste energy arguing about this anyway since there
exist at least 2 people against me here.

Nothing guarantees this, it depends a lot on what platform/what libm
as has been pointed out to me many times in the past. Please add
platform/libm to the commit message in the future.
