--- Comment #24 from jacob navia <jacob at jacob dot remcomp.fr> ---
Sorry, you are right. This is a terrible mistake FROM MY PART!

I am using the raspberry pi through ssh and I had several shells open, usin=
g my
Macintosh ARM 64 as the machine where I started those shells.

But I got confused with the Macintosh shells and thought that I was using t=
he
raspberry pi when I was using the Macintosh instead.

The macintosh compiler also is called "gcc" but actually is calling clang, =
that
doesn't support long doubles of 128 bits but only 64 bits, what explains the
loss of precision after the 15th bits!!!

The bug was in MY SIDE and I have taken your time for nothing. I am very so=
rry
about this situation. I do not know how to repair it.

My sincere excuses.
