While I'm not 100% sure about the actual fix - I'm confident enough that @rsmith can provide any further clarification in post-commit.
the test case can probably be simplified before commit - I'd suggest removing the "positive" case (the case without any diagnostics) as that's likely already covered in other tests that added this functionality to begin with, so I'd only have the case which produces the diagnostics - that should simplify/reduce the RUN lines, remove some of the #ifdefs, etc. (& potentially, you could roll the use and definition of the module into the same file as the RUN lines - so it's easier to eyeball all the relevant stuff in one place) & remove the function from the module - as this seems to produce a diagnostic even if the module is empty? Ultimately something like:
RUN: compile -DMOD_DEF to %t/module_mismatch.pcm
RUN: compile -DMOD_USE with prebuilt-module-path=%t
export module module_mismatch
(also removing the extra "prebuilt_modules" directory name to reduce the length of command line arguments, etc)
