[Vm-dev] Pinning object resets write barrier protection

[Denis Kudriashov]

Hi.

I think I found a bug:

array := {10. 20}.
array beReadOnlyObject .
array pinInMemory.
array at: 1 put: 3. "=> succeed"

Looks like pinning object resets write barrier.
Interesting that unpinning readonly object works properly:

array := {10. 20}.
array pinInMemory.
array beReadOnlyObject.
array unpinInMemory.
array at: 1 put: 3. "=> fails"


Best regards,
Denis
