   It's unfortunate that otags stops when only one file does not parse.

Indeed, the intended behaviour is drop files that cause errors
and continue tagging. Anything else is a bug.

   Fatal error: escaping exception Loc.Exc_located(_, _)
   File "ocamlsqlite/recent-orm-sqlite/hash/p4_hash.ml", line 41, characters 14-22
   Quotation.Make(Ast).Error.E(_)

This looks like a quotation parsing error. Can you try the just
release version 3.11.2? If the problem persists then please send
me the offending input file.

   Also when I run otags on files from stdlib I get:
   File "core/pervasives.mli", line 133, characters 0-8
   Camlp4 parse error: [a_LIDENT] expected after "external" (in [sig_item])

This is one of the camlp4/ocaml incompatibilities (try camlp4o
pervasives.mli!). There are more like this, see for instance
problem #5135, #5122. All we can do here is to submit bug reports
and hope that the incompatibilities get eventually fixed.

Bye,
