             Bug #: 53434
           Summary: Compiler decides declaration/expression ambiguity too
                    soon.
    Classification: Unclassified
           Product: gcc
           Version: 4.6.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: james.kanze@gmail.com


Created attachment 27459

Source code for very simple program showing the bug.

This may be the same as 37213, but the context is somewhat different.  When I
compile (simply g++ -c <filename>), I get the following error message:

bugInGcc.cc: In function 'void f()':
bugInGcc.cc:20:39: error: size of array has non-integral type 'const char [2]'
bugInGcc.cc:20:39: error: 'parameter' declared as function returning an array

Apparently, g++ is deciding in favor of declaration after seeing C()["a"],
despite the fact that a declaration cannot be followed by a . operator.
