Can you perhaps run the testsuite without bootstrapping
(configure --disable-bootstrap; make; make check) to see if there occurs some
more obvious bug than a miscompilation of genmodes? Debugging bootstrap
miscompilations via bugzilla is difficult. The miscompile might be in
bitmap_clear, perhaps there's something obvious, but a breaking testcase
is much easier.
(I do wonder though why the miscompile happens on darwin but not linux,
even though the architecture is the same)
