Perhaps since the fix for issue #57 this testcase is producing a crash.
On amd64, running with -v4 --d4 --trace-syscalls=yes this gives

[EINVAL] The process status longword is invalid or would improperly raise the privilege level of the process.
Could be unrelated, and also looks similar to issue #137
