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

gcc/ChangeLog:
