Documentation is in module Lexing: "See the documentation of type lexbuf for information about how the lexing engine will manage positions." and there it says that the lexing engine will update pos_cnum and "The other fields are left unchanged by the lexing engine. In order to keep them accurate, they must be initialised before the first use of the lexbuf".

So, immediately after creating/acquiring the lexbuf, you initialise lex_start_p.pos_fname
