On 32bit ARM systems gcc-12 will use 32bit timestamps while gcc-13 and later will use 64bit timestamps. The problem is that SYS_futex will continue pointing at the 32bit system call. This makes the futex_wait test fail like this: waiter failed errno 110 not ok 1 futex_wake private returned: 0 Success waiter failed errno 110 not ok 2 futex_wake shared (page anon) returned: 0 Success waiter failed errno 110 not ok 3 futex_wake shared (file backed) returned: 0 Success Instead of compiling differently depending on the gcc version, use the -D_FILE_OFFSET_BITS=64 -D_TIME_BITS=64 options to ensure that 64bit timestamps are used. Then use ifdefs to make SYS_futex point to the 64bit system call.
