This has to do with the abstraction I made then. We did discuss about it on Pd's forum, but it didn't occur to me that this could be the case. I'll have a look at it and get back to you.

Hmm, it does not crash when [serial_print any] is disconnected. You can quit normally.
This may be relevant:
Pd console reports no errors when communication fails when trying too fast updates (with [serial_print any] disconnected less than 30 ms).
I uploaded a similar setup (pd patch+arduino sketch) to the folder. Here it does not crash even if updates are sent every 1 ms. And the pd console starts to write error messages when the communication is too fast (starts around 7 ms).

Does it still crash if you disconnect the [serial_print-any] abstraction from [comport]?
