Hi Jaromir,Is there a scenario where it would make sense to resume a BlockCannotReturn?If not, I would suggest to protect at image side and override #resume.Le mer. 15 nov. 2023, 23:42, Jaromir Matas <mail@jaromir.net> a écrit :Hi Eliot, Christoph, All,It's known the following example crashes the VM. Is this an intended behavior or a "tolerated bug"?`[[^ 1] on: BlockCannotReturn do: #resume] fork`I understand why it crashes: the non-local return has nowhere to return to and so resuming the computation leads to a crash. But why not raise another BCR exception to prevent the crash? Potential infinite loop? Perhaps I'm just missing the purpose of this behavior...Thanks for an explanation.Best,Jaromir--Jaromir Matas
