------- Comment #7 from jakub at gcc dot gnu dot org 2005-11-08 12:18 -------
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.

FYI, I raised this error with glibc with a slightly different attachment.
http://sourceware.org/bugzilla/show_bug.cgi?id=1830 has the code Jakub refers
to.

You may want to post to the glibc bug reporting list.

Thanks. Do I have to do something to report it to the glibc maintainers or is
the issue already known by them?

This is not a gcc bug, this is a bug in glibc.

Try to compile this little program and you'll some funny behaviour.
