[Bug c++/17530] New: 4.0: failure to emit inline function

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

When the source below is compiled, gcc emits a reference to the
inline function `B::staticfunc' but not the definition:

$ ./cc1plus  -quiet x.cc
$ grep staticfunc x.s
        pushl   $_ZN1B10staticfuncEv
$

For this example, this happens only when optimization is off; when
optimization is on, everything gets completely inlined and the problem
disappears.  However, in the original source from which this example
was derived, the problem was observed even with optimization on.

Environment:
System: Linux karma 2.6.8.1 #20 Mon Sep 13 23:48:47 EDT 2004 i686 i686 i386 GNU/Linux
Architecture: i686

	<machine, os, target, libraries (multiple lines)>
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
configured with: /home/sss/gcc/gcc/configure --prefix=/usr/local/gcc --enable-threads=posix --enable-long-long --enable-languages=c,c++,f95

How-To-Repeat:

Compile the source below:

------------------------------------
typedef void (*Func) ();

struct A
{
  A (Func) {}
};

struct B
{
  static void staticfunc () {}
};

template <class T>
struct C
{
  C() : a (B::staticfunc) {}
  A a;
};

int main ()
{
  C<int> c;
  return 0;
}
