[Vm-dev] [OpenSmalltalk/opensmalltalk-vm] Primitive 64 (primitiveStringAtPut) does not fail atomically (Issue #636)

The issue occurs with ByteString but not WideString, so "'aaa' asWideString tryPrimitive: 64 withArgs: {2. $b asciiValue}; yourself" does not show the problem, but "'aaa' copy tryPrimitive: 64 withArgs: {2. $b asciiValue}; yourself" shows the unexpected modification of the receiver.

Classic squeakvm also shows the expected behavior (the difference possibly related to Character not being immediate in the V3 object memory?).

But Cog VM with V3 image also shows the same problem, so it must not be directly related to V3 versus NewObjectMemory.
