That is a great way to solve this problem given the limitation the eh_globa=
ls
has.=20

And yes the eh_globals single-threaded fallback buffer does have this probl=
em
however for RTEMS that is a corner case because something has called `exit(=
)`
on an embedded realtime system and that typically means a reset is about to
happen.

FYI Sebastian has reviewed our compiler set up as TLS was not enabled. The
architectures that support TLS should soon be switching to that.=
