Yes, they are fixed in master on GitHub. Note that there are quite a few changes since 1.4 – I can’t promise that master has ABI compatibility with the last official 1.4 release. But if you compile the new sources using the old headers (or diff and merge manually) I don’t think there will be an issue on that front.
