           Summary: -Winline points to inexistent source lines
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: bagnara at cs dot unipr dot it
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: i686-pc-linux-gnu
  GCC host triplet: i686-pc-linux-gnu
GCC target triplet: i686-pc-linux-gnu

With GCC 3.3.x and also with version 3.4 20030826 (experimental),
the compilation command

$ g++ -O2 -Winline -c BoundingBox.ii

gives

/home/roberto/ppl/ppl/src/BoundingBox.inlines.hh: In function `std::ostream&
Parma_Polyhedra_Library::IO_Operators::operator<<(std::ostream&, const
Parma_Polyhedra_Library::BoundingBox&)':
/home/roberto/ppl/ppl/src/BoundingBox.inlines.hh:63: warning: inlining failed in
call to 'bool
Parma_Polyhedra_Library::BoundingBox::get_lower_bound(dimension_type, bool&,
Parma_Polyhedra_Library::Integer&, Parma_Polyhedra_Library::Integer&) const'
/home/roberto/ppl/ppl/src/BoundingBox.cc:76: warning: called from here
/home/roberto/ppl/ppl/src/BoundingBox.inlines.hh:80: warning: inlining failed in
call to 'bool

Parma_Polyhedra_Library::Integer&, Parma_Polyhedra_Library::Integer&) const'
/home/roberto/ppl/ppl/src/BoundingBox.cc:92: warning: called from here

The problem is that lines 76 and 92 of BoundingBox.cc do not exist:
that file has only 62 lines.  In other cases (let me know if you want them)
the line given contains a comment.  More generally, the lines given very often
have nothing to do with the function calls for which (according to the
warning printed) inlining failed.
