[Bug ld/11138] New: ld: internal error when using -lstdc++ and version script before object files

[doko at debian dot org]

[forwarded from http://bugs.debian.org/562822]

I (mistakenly) tried to link a file using -lstdc++ before the object file:
$ ld --version-script=ExportMap.map -lstdc++ foo.o

However ld has crashed, and told me to file a bugreport:
ld: BFD (GNU Binutils for Debian) 2.20 internal error, aborting at
../../bfd/elflink.c line 8450 in elf_link_check_versioned_symbol
ld: Please report this bug.

Attached is a reduced testcase, to reproduce:
$ cat >ExportMap.map <<EOF
{
        global: main;
        local: *;
};
EOF
$ g++ -c x.ii -o foo.o
$ ld --version-script=ExportMap.map -lstdc++ foo.o
ld: warning: cannot find entry symbol _start; defaulting to 0000000000400610
foo.o: In function `__static_initialization_and_destruction_0(int, int)':
x.ii:(.text+0x5e): undefined reference to `__dso_handle'
ld: BFD (GNU Binutils for Debian) 2.20 internal error, aborting at
../../bfd/elflink.c line 8450 in elf_link_check_versioned_symbol

ld: Please report this bug.

If I put -lstdc++ after the object file then ld doesn't crash:
$ ld --version-script=ExportMap.map  foo.o -lstdc++
ld: warning: cannot find entry symbol _start; defaulting to 0000000000400610
foo.o: In function `__static_initialization_and_destruction_0(int, int)':
x.ii:(.text+0x5e): undefined reference to `__dso_handle'

Also if I don't use the export map it doesn't crash:
$ ld -lstdc++ foo.o
ld: warning: cannot find entry symbol _start; defaulting to 0000000000400640
foo.o: In function `__static_initialization_and_destruction_0(int, int)':
x.ii:(.text+0x5e): undefined reference to `__dso_handle'

$ ld -v
GNU ld (GNU Binutils for Debian) 2.20
