[mythtv] Kerneldeint crash with new deinterlacing code

I'm having problems with a crash in the kerneldeint algorithm, which
worked fine before the new BOB deinterlacer and all. (I'm using DVB).
The following crash occurs everytime I switch live TV to CNN (possibly
other channels too). I don't understand the deinterlacing/filter code
and this seems to be assembly code which I'm not that familiar with so
I'd appreciate some help with this. Anyone have any ideas? Thanks!
