// This tests two things: that the two calls to null_deref below are coalesced
// into a single bug by both the plist and HTML diagnostics, and that the plist
// diagnostics have a reference to the HTML diagnostics. (It would be nice to
// check more carefully that the two actually match, but that's hard to write
// in a lit RUN line.)
