O.k. - even so it _did_ work until recenty.  I just switched to the
soc branch - the C code looks much cleaner.  BUT I still get segfaults
with 'denemo -M jack -A jack' (note to Dominic Sacré: it would be nice to
mention these commandline switches in the useage help. I only found out 
about then by tracing config->audio_driver->str in the sources).

drilling down the segfault seems to apear here:

 Breakpoint 1, audio_initialize (config=0x815b438) at audiointerface.c:102
 102      if (strcmp(driver, "jack") == 0) {

Hmm.
