What do you expect the patch to do, hang Pd?
For me it prints this in the Pd 0.46.7 console:
packOSC: This packet is not a bundle, so you can't write another address
packOSC: Problem writing address.
packOSC: According to the type tag I didn't expect any more arguments.
packOSC: usage error, write-msg failed.
print: /trigger/osc/message now
It's possible to open a bundle (with a '[' message) and add multiple messages, but the OSC message is output only when the bundle is closed with the ']' message.
In your patch, if you put a [delay] after the bang outlet it will start an infinite loop at the delay interval. I'm not sure why the delay is necessary though, as [packOSC] should have finished processing the previous message by the time the next one arrives, even if it's a zero logical time delay.
