Below csd give seg fault on Ubuntu 32b when playing in RT with midi.
Problem occurs when playing around midi keys 57 to 61.
(all other STK opcodes are OK in real time)

All other STK opcodes works well.
My system is ubuntu 10.04, csound cvs float and double.
But i have seen this "problem" since about 2 years (file CsoundVST.csd in
csound examples).
First time i use gdb, hope this help.
Cheers,
René

I have managed to build STK and it runs with no errors on my Linux system
Suggested that this is an Ubuntu error. From whence came your system?

Message:
Is thi sin Csound or in the STK system? Can you run under gdb and then
with the where command isolate the function involved? I still do not seem
to be able to build the STK code due to many C++ errors, and my knowledge
of C++ is insufficient to understand it

I'have done:
rt-midi play -> midi record -> midi file -> score file --->score
instrument
and isolate a faulty section as below, i have changed the frequency to the
same values.
-Wfd -+rtaudio=null -+rtmidi=null --expression-opt
sr = 44100
ksmps = 16
instr 1 ; STK Shakers
asig STKShakers p4, 1.0, 1071, 22, 11, 1, 128, 100, 1, 30
out asig*100000
endin
i 1 10.0 0.45 261.626
i 1 10.3 0.29 261.626
i 1 10.7 0.48 261.626
i 1 11.1 0.27 261.626
i 1 11.5 0.63 261.626
This give seg fault every time i run it.

I have tried with score activated (without midi), but i don't success to
have any seg fault.
Seg fault appears if i play "fast" on my midi keyboard.
Below midi note 57 no problem
Higher midi note 61 no problem
Between 57 and 61 seg fault
Note 57 and 59 played at the same time give seg fault, most of the time
but not always!!!
I will record a midi file to test with score.
Thanks
René

Does this fail without MIDI? That is, is it the high frequency?
