--- Comment #1 from Matt Beardsley <beardsley.matt.j at gmail dot com> ---
Just wanted to clarify that the prev. comment only reproduces with an asserted
build.

However, I first observed this in a 300,000+ LOC preprocessed file with a
release gcc build. But I could not stably minimize those reproduction steps
much further below that size.

But I found I could much more consistently hit an ICE using an asserted build
instead, which seems to add up given it looks like it's an out of range access
(which is what the assert is guarding)
