So, new glibc does have a fallback timer_create() which can return 0 as a timer_id: https://elixir.bootlin.com/glibc/latest/source/sysdeps/unix/sysv/linux/timer_create.c#L150 ...but it should only be using that code if the binary was built against an old libc and then dynamically links with the new one, which is a bit of an odd setup, and I'm not sure why you run into it. -- PMM
