[sc-dev] scsynth crashes

[James Harkins <jamshark70@xxxxxxxxx>]

I've had a couple of scsynth crashes while working on my adaptive sequencing routines. It occurs after I've been running the routine for a few minutes. The routine runs normally then stops abruptly with NodeWatcher complaining about a null nodeID. At that time I notice the synth has crashed. There is no RESULT = in the output window.

I'm using the default synthdef, nothing fancy.

I haven't done a cvs update in a while so I'll rebuild now and try again after that.

Any ideas?

James
