<p dir="auto">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.</p>
<p dir="auto">Classic squeakvm also shows the expected behavior (the difference possibly related to Character not being immediate in the V3 object memory?).</p>
<p dir="auto">But Cog VM with V3 image also shows the same problem, so it must not be directly related to V3 versus NewObjectMemory.</p>
