TypeError: yylexer.mergeLocationInfo is not a function

[khmseu]

Command was "mkgrammar": "../../node_modules/.bin/jison -o asn1p_ -E asn1p_y.jison asn1p_l.jisonlex"
Version is v0.4.15-113-1680-g396e9250

Looking through the sources, I see this is called all over the place, but I don't see a definition

I need to ad a correction. Actually I got the error with version [email protected] - I was confused because I had checked out the repository right next to the version I used. However, my comment about missing a definition applies to that version, as well.
