Hi, I am wondering a bit about the state of Pharo 6 64-bit. On one hand the current RC seems to work really well on macOS (for me), it is stable and clean. Is the goal to ship this variant as a real finished version ? If so, I think must make it pass as much unit tests as possible. I filed a couple of issues related to that: https://pharo.fogbugz.com/f/cases/20102/SmallInteger-digitAt-not-ready-for-6... https://pharo.fogbugz.com/f/cases/20108/CompiledMethod-isAbstract-fails-on-6... https://pharo.fogbugz.com/f/cases/20111/Some-Collection-tests-fail-on-64-bit... https://pharo.fogbugz.com/f/cases/20110/AllocationTest-testOutOfMemorySignal... The first one has a fix. Fixes must be done carefully, since the same image must be able to run on both 32 and 64 bit. I also noticed that a couple of Compiler tests are failing. Now, obviously the compiler works good enough since it can load code, so this is probably also something minor/weird/unexpected. About 51 tests fail (in MethodMapTests, OCBytecodeHGeneratorTest and OCNewCompilerWithChangesFunctionalTests). Should I create an issue ? Sven
