jdanekrh commented on issue #459: DISPATCH-1282 - Support for building on macOS

   I think I've figured out the segfault in tests. It is problem with tests. The test provides its own fake `qd_server_timeout` in `timeout_tests.c` which must be used during the test, but under macOS, the "real" version in `server.c` is picked up. On Linux, the test version is used because of linking with `-rdynamic`. On macOS, this option is not present (looks to be noop?), so it has to be achieved differently. Don't know how.
