[Bug c++/16391] New: Segmentation fault when mixing inheritance, templates and friends


Segmentation fault when mixing inheritance, templates and friends

gcc -v returns:
Reading specs from /usr/lib/gcc-lib/i486-linux/3.3.4/specs
Configured with: ../src/configure -v
--enable-languages=c,c++,java,f77,pascal,objc,ada,treelang --prefix=/usr
--mandir=/usr/share/man --infodir=/usr/share/info
--with-gxx-include-dir=/usr/include/c++/3.3 --enable-shared --with-system-zlib
--enable-nls --without-included-gettext --enable-__cxa_atexit
--enable-clocale=gnu --enable-debug --enable-java-gc=boehm
--enable-java-awt=xlib --enable-objc-gc i486-linux
Thread model: posix
gcc version 3.3.4 (Debian 1:3.3.4-2)


This programs leads to a segfault of the compiler:

// ------ START -------
class A{};

template<typename pat1>
class B: public A
{
public:
    B(int i):i(i){}
protected:
    int i;
};

template<typename pat1> class C :
    public B<pat1>http://gcc.gnu.org/bugs.html
{
public:
    friend class A;
    C(int i):
        B<pat1>(i){}
};
// ------ End --------


Output from gcc:

gccbug.cc:16: warning: `class A' declares a new type at namespace scope
gccbug.cc:16: warning:   names from dependent base classes are not visible to 
   unqualified name lookup - to refer to the inherited type, say `class C::A'
gccbug.cc:17: internal compiler error: Segmentation fault
