I vaguely recall problems when lexer or parser code had been generated
by different binaries, when I'd changed the PATH or upgraded some
packages or something like that.  (Older branches had a related
footgun built in, see 721856ff, but you said this is master.)  The
symptom I recall was a psql that would crash in the slash lexer so may
be completely unrelated... just mentioning it since you said a clean
build did the trick.
