If you're experiencing any issues, try re-downloading. Just replaced the build with one that has a little more memory, which should address the larger allocations gcc 8.3.0 is causing.
(insufficient memory was causing opendir to fail in loader/pm on some systems, inconsistently -- this would cause patches to not apply or sysmodules to not boot. Should be fixed.)
