Summary

0007157: Using ObjectAsMethod (#primitiveInvokeObjectAsMethod) crashes VM

Description

testing ObjectAsMethod for its use in a project. This happened a minute ago:

myClass compiledMethodAt: #SomeSymbol put: 4.

myClass SomeSymbol printString "made #run:with:in: to just return self"

bang! => Access violation (read access) at 00000009

observe the SmallInteger oop (4 << 1 + 1).

Additional Information

in Interpreter>>#lookupMethodInDictionary: it does

"Check if newMethod is a CompiledMethod."

(self isCompiledMethod: newMethod)

but neither #lookupMethodInDictionary: nor #isCompiledMethod: do check for a small integer object :(
