#5733: Mythtv-0.21-fixes backend crashes on AMD64 when starting a recording from
an analog tuner

Severity: medium | Mlocked: 0
---------------------------------+------------------------------------------
I have Mythtv running on an AMD64. After I migrated from a 32bit distro to
a 64 bit distro, mythtv started crashing randomly, but always at the start
of an analog recording.
The message and important part of the backtrace:
Program received signal SIGSEGV, Segmentation fault.

For me the solution has been to upgrade the miniLZO library to the latest
version. It fixes a number of issues with 64 bit platforms. Patch
attached.
