Description Udo Steinberg 2005-02-22 20:17:18 UTC

The following program causes an internal compiler error when compiled with
gcc-3.4.3 or gcc-4.0 (CVS):

template <typename T>
class C
{
    public:
        void foo();
};

template <typename T>
void
C<T>::foo()
{
    union {
        struct {
        };
    };
};

int main()
{
    return 0;
}

Comment 1 Andrew Pinski 2005-02-22 20:22:12 UTC

Reduced to:
template <typename T>
void
foo()
{
    union { struct {  };  };
}


This is invalid code, if we do without template function we get an error:
t.cc: In function ‘void foo()’:
t.cc:8: error: anonymous struct not inside named type
t.cc:8: warning: anonymous union with no members

: Search converges between 2003-01-15-trunk (#165) and 2003-01-17-trunk (#166).

Fixed in 4.0.

Taking care of the backport to the 3.4 branch.

Comment 7 Volker Reichelt 2005-09-01 11:49:30 UTC

Fixed also on the 3.4 branch.
