Hi,
The attached patch fixes PR 81819, which popped up on GCC 7. I assume
it's also there on trunk, but can't build my app with trunk compiler
because it's got other issues.
Unfortunately I can't add the reproducer test case since it happens
only when building a bigger app with LTO. But I have confirmed that
with this fix the app builds and runs.
OK for trunk and GCC 7?
Cheers,
Oleg
