[squeak-dev] OSProcess tests crash the VM

Hi Eliot,
No dice. After I first experienced this crash in Cog, I found Cog would crash immediately upon launch. I tried again with each and every 2016 build. (I have deleted the Cog prefs .plist from my Library/Preferences and I rebooted the computer to no avail.) Thus, v3397 was the only Cog version which would still launch. This is still the case, days later.
I left this out of my bug report as I wasn't sure if it was just my computer (OS X 10.6.8) and didn't have the time/patience to retry on a newer OS X or a different user account or whatever. I do wonder if this crash is replicable (install OSProcess, run tests, find Cog no longer launches) in a different environment, but I find it unlikely anyone else would experience the same, so I didn't report it.
The Cog crash log:

What follows are the crash logs from Cocoa VM 5.7.4.1 (http://www.squeakvm.org/mac/ contains some broken links and may be quite out of date, FWIW), and Cog v3397.
