            Bug ID: 338066
           Summary: stack overflow in cmake HL
           Product: kate
           Version: 3.13.2
          Platform: Fedora RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: syntax
          Assignee: kwrite-bugs-null@kde.org
          Reporter: mw_triad@users.sourceforge.net

"custom" cpp.xml

The CMake HL causes katepart (first noticed in kdevelop, reproducible in
kwrite) to SEGV due to an infinite recursion in the HL engine. Reproducible
every time, apparently when loading the CMake HL (tested with 'kwrite
foo.cmake' where foo.cmake is an empty file).

I say this is a "custom" cpp.xml, but it's just qt4.xml renamed and with
priority=0. Thinking it's worth reporting a) as I'm suspicious if this (stock)
HL has an issue, and b) because of course katepart still shouldn't crash :-).

(If it's been fixed since, please let me know and I'll re-file as a Fedora bug
to update the RPM.)
