Bug#302989: optimizer breaks function inlining

["Steve M. Robbins" <steven.robbins@videotron.ca>]

Package: g++-4.0
Version: 4.0-0pre5
Severity: normal

Hi,

The following test code (atof.cc) elicits no warning when compiled with

  g++-4.0 -c -Wall atof.cc

but with optimization GCC complains about the standard library
function atof():

  steve@riemann{test}g++-4.0 -c -Wall -O atof.cc
  atof.cc: In member function 'double A::foo()':
  atof.cc:15: warning: control may reach end of non-void function 'double atof(const char*)' being inlined
  /usr/include/stdlib.h:378: warning: control may reach end of non-void function 'double strtod(const char*, char**)' being inlined

----------------------- atof.cc -----------------------------------

#include <cstdlib>

class A
{
public:
    double foo();
private:
};


double A::foo()
{
    return std::atof( "1.2" );
}

----------------------- atof.cc -----------------------------------

Regards,
-Steve
