I have had similar experiences but cannot describe the works/fails set so precisely. Definitely older builds worked and newer ones did not, and for me that also happened to correspond to having i386 vs amd64 machines. Do people think that it works with gcc from netbsd-5/amd64? We could add a BROKEN_FOR_PLATFORM variable to force build failures and make people aware.
