Hi Jean-Charles,
I think this is due to a change in Python 3.14:
(See https://docs.python.org/3/whatsnew/3.14.html for more context)
Citing from there:
On Unix platforms other than macOS, ‘forkserver’ is now the default
start method (replacing ‘fork’). This change does not affect Windows or
macOS, where ‘spawn’ remains the default start method.
If the threading incompatible fork method is required, you must
explicitly request it via a context from get_context() (preferred) or
change the default via set_start_method().
See forkserver restrictions for information and differences with
the fork method and how this change may affect existing code with
mutable global shared variables and/or shared objects that can not be
automatically pickled.

Hi,
I've upgraded my box to Fedora 43 one month ago, and since then am
unable to conclude a "make doc" either with or without a "-j5" on my
quad core, and either in-tree or in /build.
Would anybody have an idea?
Cheers,
