I would say the bug is that glibc/NPTL treats the stack size attribute as the
total size it should allocate, rather than as the size for actual STACK. If it
always allocated the requested stack size PLUS the amount needed for TLS, the
thread structure, and any other associated data, then this situation could not
arise.
