Some of my existing patches are causing Chuck 1.3.1 to lock-up and crash. I think I've traced it back to a possible OSC issue as the example files s.ck and r.ck seem to cause the same problem... which would make sense in that my affected patches are also using OSC events. If the patch gets going at all, removing the shred(s) also causes a crash. OSC_send.ck and OSC_recv.ck however seem to work fine. On my own patches I can sometimes catch the error message; "OutOfMemory: while allocating stack"... increasing buffer size and/or decreasing sample rate seem to alleviate the problem somewhat in that things keep running a few seconds longer, but eventually the result is the same. However, I guess this might not be the same issue as with s.ck and r.ck. Running Chuck with --silent doesn't resolve things either. My machine is Windows 7, 32-bit... to be fair it is a bit on the old side (Pentium 4)... but it's coped fine with previous versions of Chuck and miniAudicle.... and I can't replicate the issue with Chuck 1.3.0.2. Many thanks. Simon
