Try applying the patches from tickets ##13264 (in particular)
and #13263 (for another case of equivalent aborts).  This
seems to be a result gcc8 implementing the AddressSanitizer
with vectors (arguably the MythTV code is wrong, but it
happened to work previously).

Typically, if enough "works for me" reports are made on
the ticket (with no documented regressions), the devs with
commit privs are more likely to review, modify as needed,
and commit the fixes with appropriate attribution.
