[Pkg-haskell-maintainers] Bug#753299: libghc-highlighting-kate-dev: Highlighting Ocaml fails

[Samuel Hym]

Hi John,

I rechecked, using the same version of the package but on a different 
machine, different arch, just in case. But still with debian-built 
packages, and with the same result.

Here is what ghci has to say, with the full versions of the modules used:

[*** Exception: Text.Regex.PCRE.Light: Error in regex: range out of 
order in character class

You think something else might be to blame in the module stack?
Do you know if there is a way to ask pcre-light to be somewhat more 
informative about the regex producing the issue?

By the way, many thanks for pandoc!

Best regards
Samuel
