[Bug c++/13668] thread local storage: static class member does not work

Why are you so sure it is not a GCC bug?
It clearly is a C++ frontend bug:
grep -C1 _ZN5TemplImE2_tE __thread.s __threadmain.s
__thread.s-     movq    -16(%rbp), %rax
__thread.s:     movq    %rax, _ZN5TemplImE2_tE(%rip)
__thread.s-     leave
--
__thread.s-     movq    %rdi, -8(%rbp)
__thread.s:     movq    _ZN5TemplImE2_tE(%rip), %rax
__thread.s-     leave
--
__thread.s-     movq    (%rax), %rax
__thread.s:     movq    $_ZN5TemplImE2_tE, (%rsp)
__thread.s-     movq    %rdx, %r9
--
__thread.s-     movq    (%rax), %rax
__thread.s:     movq    $_ZN5TemplImE2_tE, (%rsp)
__thread.s-     movq    %rdx, %r9
--
__threadmain.s- .zero   1
__threadmain.s:.globl _ZN5TemplImE2_tE
__threadmain.s- .section        .tbss
__threadmain.s- .align 8
__threadmain.s: .type   _ZN5TemplImE2_tE, @object
__threadmain.s: .size   _ZN5TemplImE2_tE, 8
__threadmain.s:_ZN5TemplImE2_tE:
__threadmain.s- .zero   8

As you can see, _ZN5TemplImE2_tE is correctly declared as a .tbss object
in __threadmain.s, but __thread.s works with that object as if it wasn't
__thread variable.
