[mythtv-users] master: DVB-T segfaults in mythtv-setup and mythbackend

[John Pilkington]

Hi:  I now have current master 823e708 built and installed under el7; 
thanks to Gary for his taglib bump.

But it has a DVB-segfault problem which also affects the Fedora 32 box 
at ccec025, and I saw something very similar with the ubuntu 18.04 ppa 
on Thursday before that box got reconfigured (rather more drastically 
than I had intended) for other duties.

The F32 box seems normal unless in Live TV mode, when it fails to lock. 
I have tried retuning the el7 box but that segfaults before the end of 
an 'all transports' scan.  It also shows this on an in-and-out run (from 
the command line) of 'MYTHTV_NO_EGL=1 mythtv-setup'

and this is part of the result of 'mythbackend' followed by 'killall

Now I think I may try a 'yum downgrade'...
