            Bug ID: 58114
           Summary: allow turning the warning about deleting a pointer of
                    incomplete type into an error
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: tilman.vogel at web dot de

While many warning messages have a way to control their emission and treatment,
e.g. "warning: multi-line comment [-Wcomment]", some warnings do not, in
particular:

warning: possible problem detected in invocation of delete operator: [enabled
by default]
warning: 'value' has incomplete type [enabled by default]

As a consequence of being enabled by default, there does not seem to be an
associated warning class that I could pass to "-Werror=". 

I'd really like to be able to say 
"-Werror=delete-with-incomplete-type"
