This looks like a new bug, also present in gcc mainline. I'll reduce and open an upstream PR. We'll evaluate the fix once we've fixed this on trunk. Fixed upstream, will backport to gcc-8 and DTS 8.1. Patch backported to gcc-8, will be in the next update from Fedora. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory, and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. https://access.redhat.com/errata/RHEA-2019:4134 |
