Hi Eliot. I took a Pharo 1.1.1 image (which has included the changes to run Cog) and I run all the tests with the build  r2219<br><br>And these are the results:<br><br>9768 run, 9698 passes, 53 expected failures, 15 failures, 2 errors, 0 unexpected passes<br>
Failures:<br>FloatTest&gt;&gt;#testRaisedTo<br>MCInitializationTest&gt;&gt;#testWorkingCopy<br>FloatTest&gt;&gt;#testReciprocal<br>ReleaseTest&gt;&gt;#testUndeclared<br>FloatTest&gt;&gt;#testDivide<br>MethodContextTest&gt;&gt;#testClosureRestart<br>
FloatTest&gt;&gt;#testCloseTo<br>FloatTest&gt;&gt;#testHugeIntegerCloseTo<br>FloatTest&gt;&gt;#testInfinityCloseTo<br>WeakRegistryTest&gt;&gt;#testFinalization<br>PCCByLiteralsTest&gt;&gt;#testSwitchPrimCallOffOn<br>AllocationTest&gt;&gt;#testOneGigAllocation<br>
FloatTest&gt;&gt;#testNaNCompare<br>FileStreamTest&gt;&gt;#testPositionPastEndIsAtEnd<br>NumberTest&gt;&gt;#testRaisedToIntegerWithFloats<br><br>Errors:<br>MessageTallyTest&gt;&gt;#testSampling1<br>WeakSetInspectorTest&gt;&gt;#testSymbolTableM6812<br>
<br><br><br>I think that most of these problems were fixed in latest official SqueakVM. I guess they were integrated in VMMaker in versions later than the one you used for Cog. Maybe you can integrate them and create a new version?<br>
<br>I am not a VM expert so please if you can help us with this tests it would be cool.<br><br>Thanks<br><br>Mariano<br>
