[PM] Fix horrible typos that somehow didn't cause a failure in a C++11

build but spectacularly changed behavior of the C++98 build. =]

This shows my one problem with not having unittests -- basic API
expectations aren't well exercised by the integration tests because they
*happen* to not come up, even though they might later. I'll probably add
a basic unittest to complement the integration testing later, but
I wanted to revive the bots.
