Notes

sbeattie

issue in embedded copy of yajl, looks to affect upstream yajl, too

rodrigo-zaiden

as of 2023-06-07, upstream yajl hasn't fixed it, only the embedded copy in ruby-yajl got fixed. even though the code around this fix is similar between yajl and ruby-yajl, the risk of patching one based in the other could be risky without upstream support.
