cmsg test program dumps core on s390x-unknown-linux-gnu #1240
Description
PR #1235 adds a new test program to make sure that the cmsg(3) family of macros are correctly implemented. But on s390x (in qemu, of course), it fails with the cryptic error message timeout: the monitored command dumped core. It seems as though the kernel hasn't even finished booting. I only see this error in Travis. On my desktop, cmsg works fine for s390x.
