FWIW, I tried a build on Fedora 25 using the same compiler flags you
showed.  Works OK there too.  So this suggests possibly an Archlinux-
specific compiler bug, though I wouldn't want to pin blame without
more evidence.

It'd definitely be interesting to see a stack trace, if you manage
to reproduce the problem in a debug-enabled build.
