The check that fails is: https://github.com/targos/node/blob/bfbf0b64551ee22acc30d5cd66d7f6b5eae97c04/deps/v8/src/objects/js-array-buffer.cc#L76-L78

  DCHECK_IMPLIES(
      !backing_store->is_wasm_memory() && !backing_store->is_resizable(),
      backing_store->byte_length() == backing_store->max_byte_length());

It's a new check in this version.

/cc @addaleax ?

targos · 2021-09-04T15:59:12Z

Added in v8/v8@1e7effd

addaleax · 2021-09-05T21:45:59Z

@targos I think https://github.com/v8/v8/blob/1e7effd113d791f2272160e0e41e048b39892dc6/src/objects/backing-store.cc#L778 is just missing a line for max_byte_length_ = new_byte_length, i.e. it’s a bug in the commit you referenced.

targos · 2021-09-06T06:25:21Z

/cc @marjakh ^

marjakh · 2021-09-06T07:07:41Z

Right, that seems to be the case. I'll fix this upstream, thanks for pointing this out! (Slightly concerning that our tests didn't catch this...)I

ok the failing one is 11.2.something and the nearform is 11.6 so I think it might be fixed with an update - cant confirm right now as the macstadium ones picked the moment I began looking into to fall off the network. Also the release machine is running 11.0 so that may need an update
