BUG: Segmentation fault

I do not understand why. Motion 3.10.1 compiled by another person on Doug computer processor brcm47xx started normally. Compiled by me under the Motion 3.11.1 or trunk on a personal computer running on a brcm47xx no cross-compilation of course I do. FFmpeg version under which the intended movement and Motion 3.10.1 3.11.1 or trunk are the same.

Hi Pavel,

Hard to guess what the issue without config files or a backtrace from core dump :

Without some feedback this cannot be fixed.
