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:

Hi Tim,

   3397 is really old.  Please download more up2date VMs from mirandabanda.org, i.e. http://www.mirandabanda.org/files/Cog/VM/VM.r3732

Hi all,

I installed OSProcess into a 4.6 image via SqueakMap this morning and ran its tests.  I am running OS X 10.6.8.  Early into the list of tests to run, the VM crashes.  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are the crash logs from Cocoa VM 5.7.4.1 (http://www.squeakvm.org/mac/ contains some broken links and may be quite out of date, FWIW), and Cog v3397.

Here is the crash log from 5.7.4.1:
