They also want us to try: (10:44:14 AM) jakub_: sgallagh: that said, as usually I'd suggest them to try - -fsanitize=undefined, various packages e.g. call methods on NULL pointers which is invalid C++ (10:45:07 AM) jakub_: sgallagh: and/or try -fno-delete-null-pointer-checks , - -fno-strict-aliasing, -fno-aggressive-loop-optimizations , -fwrapv etc. if it makes a difference Once I have a reproducer, I can try doing some builds with those flags and see what happens. Please file a BZ to track this and add the information there. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iEYEARECAAYFAla6CfEACgkQeiVVYja6o6O5dACbB3TwemQgAaEMg0oZdNaHZAnj HRsAn2c7CiakcapDKW/Po/d7aY4fQMIC =jwZa -----END PGP SIGNATURE----- _______________________________________________ nodejs mailing list [email protected] http://lists.fedoraproject.org/admin/lists/[email protected]
