Unfortunately after several minutes of playing the service breaks
with the message

diskin2: opened '/home/anton/Seashore.wav':
         44100 Hz, 2 channel(s), 546731 sample frames
*** Error in `csound': double free or corruption (out): 0x00000000014bfd70 ***
Csound tidy up: Aborted

Any ideas?

It's done. Just in case if anyone interested in the end result.

I post a code for service. It can play continuously wav files 

on several channels. Channels are identified by numbers.

User can for the given channel

* start playing a wav file in the loop. The wav files are played with xfade at the ends

   so that user percieves it like a continuous flow.

* stop playing a file

* resume playback

* set the volume for the given channel

* set a global fade in/out time

Also there is a python file that makes it easy to trigger the service

from the code. There are some test remnants of file names you can

substitute it with your own files.

This combo of OSC service and python client makes it easy

to livecode with python.

How to do it?

2016-01-24 1:06 GMT+03:00 Victor Lazzarini <Victor.Lazzarini@nuim.ie>:

Can you run it under a debugger?

Discussions of bugs and features can be posted here

A couple of things that may (or may not) be useful:

1. This post discusses the victim error message:

http://stackoverflow.com/questions/9123064/int-malloc-assertion-error

2. There is an i-time if-then used that wraps perf-time code (the

    ichan filenchnls gSFiles[iChannel]
    kchan init ichan
    if (kchan == 1) then

Interesting, that's the opposite of what I was expecting. I guess I
need to review what's happening there.  I had thought that maybe both

Trying separate instruments for mono and stereo could be interesting
to have more information.

One other off-chance possibility, I noticed the libsndfile in the trace is in:

/usr/lib/x86_64-linux-gnu/libsndfile.so.1

but csound is in:

/usr/lib/libcsound64.so.6.0

Any chance one could be 32-bit (i686) and the other 64-bit (x86_64)?
I'm not sure if that'd even runtime link...

What version of libsndfile and csound are being used?
