[Vm-dev] Why does CompiledMethod>>#objectAt:put: work no longer on spur?

[Tobias Pape]

In V3, this works:
| cm |
cm := (CompiledMethod newFrom: (ByteString >> #findSubstring:in:startingAt:matchTable:)).
cm objectAt: 1 put: (cm header bitAnd: 16r1FF bitInvert).

In SPUR, objectAt:put: raises a primitive Failed.
