            Bug ID: 24192
           Summary: ld doesn't properly process relocations to
                    deduplicated code in PE files
           Product: binutils
           Version: 2.32
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

$ cat x.cpp
class a {
  virtual void c();
};
inline void a::c(){}
$ i686-w64-mingw32-g++ -g -c x.cpp -fno-rtti -o x.o
$ objdump --dwarf=decodedline -r -j.debug_line x.o

x.o:     file format pe-i386

Contents of the .debug_line section:

CU: x.cpp:
File name                            Line number    Starting address    View

$ i686-w64-mingw32-ld x.o x.o -o x.exe
$ objdump --dwarf=decodedline -r -j.debug_line x.exe

x.exe:     file format pei-i386

Contents of the .debug_line section:

CU: x.cpp:
File name                            Line number    Starting address    View
x.cpp                                          4            0x401000
x.cpp                                          4            0x401009
x.cpp                                          4            0x40100c


CU: x.cpp:
File name                            Line number    Starting address    View
x.cpp                                          4                   0
x.cpp                                          4                 0x9
x.cpp                                          4                 0xc


This has the same symptoms as bug 24191.  Compiling with -fno-rtti is not
necessary to reproduce this, it just makes the link line simpler and the
objdump output shorter.  This also happens when ld is run indirectly via g++.
