Cog VM binaries as per VMMaker.oscog-eem.152/r2538http://www.mirandabanda.org/files/Cog/VM/VM.r2538/ . Fix tricky context state bug that can cause crashes in the GC. Contextpart>runUntilErrorOrReturnFrom: may pop the last argument. Hence if a frame is married in this state its spouse context won't have its last argument slot initialized. If later the frame is divorced and the arguments are not updated the last argument slot can be left with this uninitialized slot and ... bang. The solution is to update arguments as well as stack contents when divorcing. This is good also because it removes the VM's assumption that method arguments are read-only, and that's only enforced by the Smalltalk bytecode compiler, not by the bytecode.
