The MythTV lists have had several reports of problems apparently arising from new (and improved) vector-validation in gcc8. Is there a temporary
workaround?

If you don't provide details (links to the reports, etc.), then it is
impossible to tell anything.

As I said, the bug-tracker is currently out of action. Here's the original
report:

http://lists.mythtv.org/pipermail/mythtv-commits/2018-May/117389.html

If mythtv invoked UB, then you really just want to fix the UB, not look for
workarounds.

Agreed. But it seems unlikely that MythTV will be the only programme affected, and people who rely on packaged builds won't immediately have that option. I'm still on F26...and SL7


In fact, lilypond is another package affected:
