           Summary: private module members have global bindings instead of
                    local ones
           Product: D
           Version: 0.170
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Keywords: link-failure
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: thomas-dloop kuehne.cn

 Private means that only members of the enclosing class can access
 the member, or members and functions in the same module as the
 enclosing class. Private members cannot be overridden. Private
 module members are equivalent to static declarations in C programs.


=== d.d ===
private void foo(){
}
======

dmd -c d.d
readelf -s d.o

 Symbol table '.symtab' contains 11 entries:
 Num:    Value  Size Type    Bind   Vis      Ndx Name


<snip>

  10: 00000000     5 FUNC    GLOBAL DEFAULT   12 _D1a3fooFZv


=== c.c ===
static void foo(){
}
======

gcc -c c.c
readelf -s c.o

 Symbol table '.symtab' contains 11 entries:
 Num:    Value  Size Type    Bind   Vis      Ndx Name


<snip>

   5: 00000000     6 FUNC    LOCAL  DEFAULT    1 foo



This becomes a problem if a private function with C calling convention
is defined:

=== bug.d ===
private extern(C) void foo(){
}
======

dmd -c bug.d

 Symbol table '.symtab' contains 11 entries:
   Num:    Value  Size Type    Bind   Vis      Ndx Name


<snip>

 10: 00000000     5 FUNC    GLOBAL DEFAULT   12 foo


The last line should have been

 10: 00000000     5 FUNC     LOCAL DEFAULT   12 foo

I could be wrong, but I don't think that "equivalent to static" meant it's
equivalent in how the two are emitted to the object, but rather where they can
be used from (i.e. from within a single module).
