Building mplayer with current gold, it segfaults on start.
The reason was this version script:

= = = = = = = = =

MPLAYER_1 {
  # to support glibcs abhorrent backwards-compatibility hack
  global: _IO_stdin_used;
  local: *;
};

= = = = = = = = =

Which resulted in this:

$ readelf --syms --use-dynamic mplayer

Symbol table of `.gnu.hash' for image:
  Num Buc:    Value          Size   Type   Bind Vis      Ndx Name
  631   1: 0000000000000000     0 OBJECT  GLOBAL DEFAULT ABS MPLAYER_1



Now ld.bfd doesn't do this, and it's a regression, which I narrowed down
to the fix for PR gold/18548 https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commitdiff;h=5417c94d1a944d1a27f99240e5d62a6d7cd324f1
Because this is the result after reverting that patch:


$ readelf --syms --use-dynamic mplayer

Symbol table of `.gnu.hash' for image:
  Num Buc:    Value          Size   Type   Bind Vis      Ndx Name
  628   0: 00000000015ac8c0     8 OBJECT  GLOBAL DEFAULT  29 stdout
  629   0: 00000000015ac998     0 NOTYPE  GLOBAL DEFAULT ABS _end
  630   0: 0000000000fc7450     0 NOTYPE  GLOBAL DEFAULT ABS _edata
  631   0: 0000000000000000     0 OBJECT  GLOBAL DEFAULT ABS MPLAYER_1
  632   1: 00000000015ac8e0     8 OBJECT  GLOBAL DEFAULT  29 stderr
  633   1: 00000000015ac900   152 OBJECT  GLOBAL DEFAULT  29 vpx_codec_vp8_dx_algo
  634   1: 0000000000fc7450     0 NOTYPE  GLOBAL DEFAULT ABS __bss_start



And here is the result of ld.bfd, the result that the patch presumably meant to generate:

$ readelf --syms --use-dynamic mplayer

Symbol table of `.gnu.hash' for image:
  Num Buc:    Value          Size   Type   Bind Vis      Ndx Name
  629   0: 00000000011c34a0     8 OBJECT  GLOBAL DEFAULT  28 stdout
  630   0: 0000000000000000     0 OBJECT  GLOBAL DEFAULT ABS MPLAYER_1
  631   1: 00000000011c34c0   152 OBJECT  GLOBAL DEFAULT  28 vpx_codec_vp8_dx_algo
  632   1: 00000000011c3560     8 OBJECT  GLOBAL DEFAULT  28 stderr


Workaround with gold is to add stdout and stderr to global in the version script.
