Segfaults and "Corrupt data detected, please check connection to PPK. Error: Measurement range not detected", related?

[jacobrosenthal]

Im getting a lot of segfaults in like.. one out of three or five runs.

Im not using electron, just a custom little script automating some power profiling. In all modern version s of node (7, 8 and 9) on macos 10.13.4 (17E202)

Starting to try to track them down myself but thought Id post here as well

sometimes it manages to get an error out prior to segfaulting. Im guessing "Measurement range not detected" is from the ppk_nrfconnect.hex firmware. Is that source available somewhere?

other times not. Same crash maybe? or different.

@bencefr Thanks for jumping on this for me, but dont merge yet unless you like that code otherwise.. Ive been working on it for ages, but it turns out I wasnt returning promises from hapi's lab framework correctly.

Im sure ie seen a few other segfaults from before I switched to lab. Ill be happy to report the next one I see :)

Thanks!

Thanks @jacobrosenthal , I'm happy that you confirmed this is the same issue we have also hit.
