Thanks for looking into this.

This is 'expected', since (this version of?) g-ir-compiler doesn't know
about __float128 as a built-in type.
There's no input which can legitimately make gcc terminate with segv, so
trying to blame this on gobject-introspection is incorrect. There is a
something going wrong in gcc, or (more probably) cygwin.
From previous reports [1], [2] it seems to be a problem which only
manifests itself on WOW64.

I think it just didn't get far enough, the same error is seen when
building locally (which is how I had to build the package, because of
the 'signal 11' problem)
