I just did a complete clean build just to be sure and it had the same
crash. The same crash happened. Here's the output from ldd grepped for qt:

So it looks like you already pointed out that the Qt4 libraries are being
linked in as well for some reason. Any ideas on what I should do to run
down where this issue is coming from?

I reverted that commit and it built without me specifying the path to
lrelease-qt5.
