No problem. I rather prefer that being a compile issue than an actual crash in
a core part of KWin.

Well I just switched *from* gcc-4.8 *to* gcc-5.3.1 (which does support C++14).

But you're right, this must have been a miscompilation. I rebuilt kwin from
scratch and the problems are gone.

This is weird, I was pretty sure I had wiped out the builddir when switching to
gcc5...

Sorry for the noise.

There is nothing in that code which would explain a crash.

I think your crash must be somewhere else. What I notice is that you use a
rather old compiler. KWin requires C++14.
