             Bug #: 13099
           Summary: Incorrect check for .gnu.linkonce section
           Product: binutils
           Version: 2.22 (HEAD)
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ld
        AssignedTo: address@hidden
        ReportedBy: address@hidden
    Classification: Unclassified


elflink.c has

     if (CONST_STRNEQ (name, ".gnu.linkonce.")
          && ((p = strchr (name + sizeof (".gnu.linkonce.") - 1, '.')) 
              != NULL))
        p++;  

For

(gdb) p name
$12 = 0x8750ba ".gnu.linkonce.this_module"
(gdb)

strchr is called on

(gdb) p name + sizeof (".gnu.linkonce.") - 1
$13 = 0x8750c8 "this_module"
(gdb) 

Instead we should pass

(gdb) p name + sizeof (".gnu.linkonce.") - 2
$14 = 0x8750c7 ".this_module"
(gdb) 

to strchr.
