If is a BUG, it seems at compilation time as it produces binary with
different behaviour than before.
I was not able to segfault the old binary, I have problem in
all new built binaries.

I assume the 1909 build 18363.592 2020-01-14 arisen it.

As Octave uses gnulib, it is possible that the changes in MS are causing
a different subset of gnulib to be used than before, may be exposing
a latent bug or race.

Unfortunately my old build tree was polluted by mistake, so I can
not directly compare a good build tree versus a failing one.

Just noticed that MS released yesterday a 18363.628 2020-01-28
unusually just 2 weeks after previous one.
