Replying to [comment:5 brendan@…]:
> I was having the same failure on an Intel Atom system with Arch Linux
i686 (32bit). Running with QT5.7 was fine but CPU usage went up to 100%
on QT5.8 before the backend failed with a segfault. Today, I upgraded the
same system to x86_64 with QT5.8 and the backend runs fine. This would
seem to imply that the issue is with the 32 bit version of QT5.8.
Similar setup here (Arch Linux, 32-bit), and I'm still having this issue
even after updating to the latest mythtv and QT5.8. (Dual-core Intel has
80% CPU on both cores from mythbackend with entire system lagging.)
Reverting to QT5.7 restores functionality. This would seem to confirm
there's still an issue with 32-bit QT5.8?
