In https://golang.org/cl/7797 I attempted to use myimportpath to set the value of the go.importpath.$foo. symbol for the module being compiled, but I messed it up and only set the name (which the linker rewrites anyway). This lead to the importpath for the module being compiled being "". This was hard to notice, because all modules that import another define the importpath for their imported modules correctly -- but main is not imported, and this meant that the reflect module saw all fields of all types defined in the main module as exported. The fix is to do what I meant to do the first time, add a test and change the go tool to compile main packages with -p main and not -p command-line-arguments.
