Is this fixed in master upstream, or reported?

Which release are you intending to pin to exactly? 2.3.0.0?

[shlomizadok]

@dLobatog found the issue on parser and is about to submit a patch.

Rubocop on test passes, would you like me to pin it to 2.3.0.0 specifically?

[dLobatog]

2.3.0.2 is good too, the issue is that they tried to introduce a cache for line reading in parser on 2.3.0.3 - whitequark/parser@1779727 but the hash is not initialized under some conditions, hence it fails.

[domcleal]

Yes, pinning to a more specific version would be better (.2 preferably), it's slightly unclear to me what 2.3 means otherwise.

[shlomizadok]

Done. Thanks for the input.

[dLobatog]

whitequark/parser#271 has been filed now, will merge if green, thanks @shlomizadok

[dLobatog]

Rubocop is green, don't think we need to wait for tests to finish as this gem is exclusively used by Rubocop.

[dLobatog]

Merged as 9dfe1fe, thanks @shlomizadok!
