--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I don't think your claims are based on anything in the standard.
The standard clearly says that it is implementation defined if non-block
thread_local vars are dynamically initialized right away or deferred and
initialized on first non-initialization odr-use.  The latter is what GCC
implements.=
