Hi Milian,

I know the future of KDevelop 4, just as well as you know, I hope, the current state of KF5 on OS X. We're MONTHS away of being able to use KF5 there, so while 1 (ONE) person works on basic KF5 support the others on the KDE-Mac team concentrate on improving KDE4 on OS X. We do aim to do that in a forward-looking way, so anything we do ought to benefit KF5 too.
So these are not simple bugfixes for my own personal use, but for the use of anyone who wants to use KDE on OS X (as well as possibly the legions of Linux users with distros that stick to KDE SC 4 until they judge KF5 ready ... which AFAIK is still the case for the brunt of them).

I presume that the changes I present here will carry over rather directly to git/HEAD. 

You're right though about lldb, and I was about to ask on #kdevelop if there were any plans to support that debugger outside of OS X (because I simply don't have the resources to do that alone). I just had a peak at Qt Creator: it uses Python bridges to talk with the 2 browsers, maybe an idea?

In order not to duplicate more code than necessary I changed the logic of `ptyfd`'s initial value slightly, allowing to distinguish between uninitialised and error return values.

Once that's done, the debugger component starts correctly, and appears to communicate with the gdb ("ggdb") slave process up to the point where the GUI is loaded and seemingly ready to go.
