Yes, no problems when --without-native-compilation is passed to
configure.

I tried the latest master (a902156068), and the issue remains.

Yes, issue remains with 0eba9cf651.

I will try the ideas above and report back.

It seams that downgrading to GCC 12 is the way.  Upgrading from GCC 11
to 12 went really smooth, so I didn't expect this kind of issues.  I
hope that someone more knowledgeable than me could report this to the
GCC folks so they can have a look at it.
