I originally left a comment complaining that there was no sane default value to use here, but then removed it, deciding the initial value should be good enough. But I notice Mark has left a similar complaint about an equivalent change in bug #186798. This probably requires further discussion with the JSC developers, perhaps in that bug, to decide how to fix this specific instance, as well as your two changes in WasmValidate.cpp. Looks like there is considerable overlap between the fixes in these bugs, at any rate.
