Bug: JSON.parse(undefined) reboots the ESP8266

I know that this conversation is in the 8266 realm, but - for curiosity - I just tested on a PICO, and that is what I get:

...comparable what the (Chrome) browser JS Engine throws at me: see attached screen shot (...but is for sure not a crash of the system / HW).

Workaround is asking if undefined before parsing... (try catch does not help)...
