[Bug pending/16313] New: Function's address automatically taken

["gcc-bugzilla at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

NOTE: Defaulting component because reported component no longer exists

Consider the following piece of code:

void foo (){}

template < typename T >
void
bar (const T &arg)
{
  (void) arg;
}

int
main ()
{
  bar (foo);
}

G++ 3.3, 3.4, and ICC 7.1 consider it invalid: bar (foo) must be
written bar (&foo).  Nevertheless 3.5 accepts it.  I'm tempted to say
this piece of code is invalid, but IANALL :)

Environment:
System: Linux nostromo 2.4.25 #2 Mon Mar 15 12:03:26 CET 2004 i686 GNU/Linux
Architecture: i686

	
host: i486-pc-linux-gnu
build: i486-pc-linux-gnu
target: i486-pc-linux-gnu
configured with: ../src/configure -v --enable-languages=c,c++,java,f95,objc --prefix=/usr/lib/gcc-snapshot --enable-shared --with-system-zlib --enable-nls --enable-threads=posix --without-included-gettext --disable-werror --enable-__cxa_atexit --enable-clocale=gnu --enable-libstdcxx-debug --enable-java-gc=boehm --enable-java-awt=gtk i486-linux-gnu

How-To-Repeat:

~/tmp % icc foo.cc
foo.cc(18): error: no instance of function template "bar" matches the argument list
            argument types are: (void ())
    bar (foo);
    ^

compilation aborted for foo.cc (code 2)
~/tmp % g++-3.4 foo.cc
foo.cc: In function `int main()':
foo.cc:18: error: pas de fonction concordante pour l'appel de «bar(void (&)())»
~/tmp % g++-3.5 foo.cc
