I've mostly ignored 64 bit Pharo because I can't get Iceberg stable
enough.�� Since you're also using Ubuntu 16.04, could I ask you to try
(obviously somewhere it is OK to crash the vm :-)):

Now first up, is it just Ubuntu 16.04 with this problem?

Can other Linux users report what they get for this?

| pharoRepository |

Iceberg enableMetacelloIntegration: true.
Metacello new
�� repository: 'github://akgrant43/pharo-akgosprocess/mc';
�� baseline: 'AKGOSProcess';
�� load.
pharoRepository := IceRepository registry detect: [ :each | each name
= 'pharo-akgosprocess' ].
pharoRepository pull.

And let me know the result.�� I get:

pharo: malloc.c:2394: sysmalloc: Assertion `(old_top == initial_top
(av) && old_size == 0) || ((unsigned long) (old_size) >= MINSIZE &&

0)' failed.

Ran your script and Pharo crashed with the following in the console shell...
