Bug #1842: mspec で SIGABRT

chkbuild のログを見ると mspec で SIGABRT が出ていますが、lib/mspec/mocks/mock.rb の一部の
          SpecExpectation.fail_with(
            "Mock '#{name_or_inspect obj}' expected to receive '#{key.last}' " \
            "#{qualifier.to_s.sub('_', ' ')} #{count} times",
            "but received it #{proxy.calls} times")
というところで発生していて、さらに絞り込んでみたところ、
"#{}""#{} "
で再現するようです。
