isolated to just 2 objects. steps to reproduce:

1. turn on audio processing in dsp status

4. connect cycle's output to rect's "sync input" on the right

machine running max msp jitter m4l 5.1.7 on os x 10.5.8 macbook 2.4ghz core 2 duo

tried on a mbp running 10.6.4 and it does not crash.

not complaining or anything but i accidently made this connection right in the middle of a slightly arrogant "look how cool max is" demo. lost the patch and nerds laughed at me.

Max crashed after ±30s on my iMac under X.6.6., same crashlog.

Same here. Max 5.1.8, macbook pro core 2 duo 2.8 ghz, os x 10.6.6

Thanks - I can reproduce. Looks like it is Mac only.
