I've tested with debian and lubuntu running on ARM. In both cases gcc
4.6.3. I have no x-compiled jack but compiled it directly on the ARM
system itself:

  gcc (Debian 4.6.3-11) 4.6.3
  gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3

/vanialla/ jack1, as well as /vanialla/ jack2 both fail with a "Bus
error" on startup. I have not investigated jack1, but in jack2's case

either https://github.com/x42/jack2/commits/nopackedstructs

or simply adding

#ifdef __ARMEL__
    #undef POST_PACKED_STRUCTURE
    #define POST_PACKED_STRUCTURE
 #endif

worked around the issue and jack runs fine.
