The following snippet successfully calls sleep(3) but aborts shortly after: require 'alien' local libc = alien.default libc.sleep:types('int', 'int') print "foo" libc.sleep(3) print "bar" With clang -O0 a crash can be seen instead: (gdb) r Starting program: /usr/local/bin/lua52 test.lua [New LWP 101132] [New Thread 801c06400 (LWP 101132)] foo Program received signal SIGSEGV, Segmentation fault.
