Comment at:
test/std/thread/thread.threads/thread.thread.class/thread.thread.member/detach.pass.cpp:73
assert(!t0.joinable());
while (!done) {}
assert(G::op_run);
----------------
I don't immediately see how the race on n_alive/op_run happens. It seems that
the modifications in the thread happen before this line, and modifications in
main happen after this line. How can both of them modify the variables at the
same time?
