nrfjprog 10.3.0 segfault

[nrbrook]

Running nrfjprog 10.3.0 on macOS 10.14.6 (18G87) with an nRF52 dev kit

$ nrfjprog --eraseall
Segmentation fault: 11

Occurs on all 10.x releases of Nordic command line tools. Other switches such as -i work.

$ nrfjprog -v
nrfjprog version: 10.3.0
JLinkARM.dll version: 6.48b

edit: actually, this is occurring even on 9.x versions. Something must have changed on my system. I ran homebrew upgrade, perhaps that did it. Any suggestions?

I had pin 21 connected to ground. I guess this was causing infinite reboot. It probably shouldn't cause a segfault in nrfjprog, but I've solved this issue.
