The __platform_wait function is supposed to wait until *addr != old. The futex syscall checks the initial value and returns EAGAIN if *addr != old is already true, which should cause __platform_wait to return. Instead it loops and keeps doing a futex wait, which keeps returning EAGAIN. libstdc++-v3/ChangeLog: PR libstdc++/97936 * include/bits/atomic_wait.h (__platform_wait): Return if futex sets EAGAIN. * testsuite/30_threads/latch/3.cc: Re-enable test. * testsuite/30_threads/semaphore/try_acquire_until.cc: Likewise. |
