Which, presumably, succeeded [repeatably?] (also presumably with some failing tests, since we don't have a clean testsuite on macOS). I then applied the patch, configured, "make; make > -k check" and the make check always stops with > > <stuff removed> > Running > /Users/lucier/programs/gcc/gcc-mainline/libstdc++-v3/testsuite/libstdc++-dg/ > conformance.exp ... > WARNING: program timed out. There's not quite enough information here - it would be useful to know which test(s) timed out - running "make check -jN -k" (where N is some sensible number for the cores on your machine) would help since that will then print which tests timeout. > Sorry, I don't know what's going on. The proposed patch is experimental - I haven't had an opportunity to test it across the range of platforms - it might be incomplete or incorrect.
