KWin sometimes gets into a mode when it always crashes on start if desktop effects are enabled. This happens on Haswell hardware.

00:02.0 VGA compatible controller [0300]: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller [8086:0412] (rev 06)

The crash looks as follows:

Huh, I've never seen this failure mode.  But it sounds entirely plausible.

The X server's GLX code has a bug where it may randomly return a bogus visual/fbconfig; perhaps it ended up not having stencil, and we crashed?

That bug is fixed in X server git, and the upcoming 1.15.1 and 1.14.6 releases (due any day now).  Alternatively, you could try asking KWin to use EGL:

   KWIN_OPENGL_INTERFACE=egl kwin --replace &

Does either of those fix this issue for you?

Tested by applying eec04d76a39a7334de4e00ef9f0f6e44c92b3d91 on top of 1.15.0. Cannot reproduce the bug anymore.
