Created attachment 36827
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=36827&action=edit
source file that reproduces the bug (data race fixed)

I've uploaded again the source file with the fixed data race (typo when
writting the example, sorry).

Now it passes both -fsanitize=thread and -fsanitize=address (but still does not
work as expected).
