Puck.js Execution Interrupted during event processing. New interpreter error: CALLBACK,MEMORY

The example comes from here: http://www.espruino.com/Puck.js+Infrared.

Here's the output of process.memory() before and after loading the code.

process.env follows.

process.memory()
={ free: 2217, usage: 33, total: 2250, history: 12,

"flash_code_start": 442368, flash_length: 524288 }
