             Bug #: 50054
           Summary: Fails to recover from type error in function signature
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: stiffy2@gmx.de


GCC fails to recover from the type error in the function signature of g and
crashes:

void g( const int& (a)[1] ) {}

int main () {
    g( { 1, 2 } );
}

It doesn't crash when g( { 1, 2 } ); is deleted.

================ Using 4.7

Call to GCC with error message:

% LANG=C make CXXFLAGS="-std=c++0x" listinit
g++ -std=c++0x    listinit.cpp   -o listinit
listinit.cpp:1:25: error: declaration of `a' as array of references
listinit.cpp: In function `int main()':
listinit.cpp:4:17: internal compiler error: in cxx_incomplete_type_diagnostic,
at cp/typeck2.c:453
Please submit a full bug report,
with preprocessed source if appropriate.
