--- Comment #5 from Dmitry Vyukov <dvyukov at google dot com> ---
Markus, how do you configure and build gcc? Is there anything special?

Our tls accesses should not go through __tls_get_addr because we use
initial-exec attribute. __tls_get_addr vs indirect access through got is chosen
by compiler, right? So it's not linker. The question is why does your compiler
chooses to use the call... If I am not mistaken,
__tsan::ScopedInterceptor::ScopedInterceptor should have been already accesses
cur_thread, and that did not crash, which suggests that there is no
__tls_get_addr call.
