OpenBSD 6.7 Is it working?

[j4n3b]

I successfully built the fsnotifer on openbsd 64bit 5.7 installation. but running it returns

 ./fsnotifier --selftest             (*master+12) 05:56:59 
fsnotifier[19793]  info: started (self-test mode) (v.20160218.1844)
fish: './fsnotifier --selftest' terminated by signal SIGABRT (Abort)

I also set the watcher as you said in intellij custom property but I get the same error file watcher would be slow ...
