I don't see why you're saying it's impossible - because you haven't posted any
code. In any case, it's not the point of this list, so don't post the code
here. Post to your vendor's bug tracker.

In https://codebrowser.dev/glibc/glibc/nptl/pthread_detach.c.html, there is no
direct access to global data. The only possibility is in that call to
__nptl_free_tcb → __nptl_deallocate_stack → queue_stack, which can only happen
if the thread in question has been cancelled... but you didn't mention
cancellation and std::thread doesn't have that ability anyway.
