Hello,

I'ld like to add that if I comment all lines in the "callback" function (as if it was empty), I get the same error (11) again.

Regards
vuott

 1. Have you confirmed that the
 example made in C really works?
 
 2. You should confirm size of jack_default_audio_sample_t.
 Mistakes with
 memcpy doesn't always lead to SGN11.
 Since memory area you are writing over, may be owned by the
 program doing
 the mistake. That often causes random
 behaviour.
 
 3. Cannot lock down 82274202 byte memory area (Cannot
 allocate memory) ??
