Calling one of pthread join/detach interceptor on an already joined/detached thread causes asserts such as: AddressSanitizer: CHECK failed: sanitizer_thread_arg_retval.cpp:56 "((t)) != (0)" (0x0, 0x0) (tid=1236094) #0 0x555555634f8b in __asan::CheckUnwind() compiler-rt/lib/asan/asan_rtl.cpp:69:3 #1 0x55555564e06e in __sanitizer::CheckFailed(char const*, int, char const*, unsigned long long, unsigned long long) compiler-rt/lib/sanitizer_common/sanitizer_termination.cpp:86:24 #2 0x5555556491df in __sanitizer::ThreadArgRetval::BeforeJoin(unsigned long) const compiler-rt/lib/sanitizer_common/sanitizer_thread_arg_retval.cpp:56:3 #3 0x5555556198ed in Join<___interceptor_pthread_tryjoin_np(void*, void**)::<lambda()> > compiler-rt/lib/asan/../sanitizer_common/sanitizer_thread_arg_retval.h:74:26 #4 0x5555556198ed in pthread_tryjoin_np compiler-rt/lib/asan/asan_interceptors.cpp:311:29 The assert are replaced by error codes.
