Perhaps we should just remove the assert:

r266816 is already present gcc-9-branch but it didn't fix the ICE.  I'm afraid
it's r272125, but alas that doesn't seem to be backportable.

Confirming that latest GCC 9 still ICEs.

Anything I can do to help resolve this? We have library code that breaks
because of the issue and since 9.2 is deployed everywhere that 9.1 was used,
this is very disruptive...

Thank you!

That's why I haven't closed the PR.

Trunk seems to emit a potentially bogus error, reducing that.

But not for GCC9? 

I can confirm that GCC 9.2.1 snapshot from 20190817 still triggers the bug.
