           Summary: etc.c.zlib must be nothrow
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: trivial
          Priority: P1
         Component: Phobos
          Assignee: nobody@puremagic.com
          Reporter: ketmar@ketmar.no-ip.org

as etc.c.zlib is just an interface to C code, everything there should be marked "nothrow".

and, for that reason, "@trusted" too, 'cause ZLib tries hard to validate it's input data.
