Subject: [Bug c++/16558] New: 3.5: bogus missing-return warning
X-Bugzilla-Reason: CC

g++ mainline erroneously warns about a missing return for the code below.

$ g++ -c -Wall x.cc
x.cc: In function `int getref(int)':
x.cc:17: warning: control reaches end of non-void function
$

Environment:
System: Linux karma 2.6.7 #18 Wed Jul 14 03:27:01 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:

-----------------------------------------
struct C
{
  C ();
  ~C ();
};

int getref (int ndx)
{
  C d;

  if (ndx != 0) {
    C base;
    return 0;
  }
  else
    return 0;
}
