Lionel's original patch can still be applied (with line number shift).

  if (link_info.version_info != NULL
  && (name[0] == '\0' || link_info.version_info->name[0] == '\0'))
{
  einfo (_("%X%P: anonymous version tag cannot be combined"
   " with other version tags\n"));
  free (version);
  return;
}


This is an arbitrary and non-meaningful restriction to me.

(The original problem had been solved in LibreOffice with

"fdo#42865: privatized unique empty string symbol," i.e., adding
_ZNSs4_Rep20_S_empty_rep_storageE to the version maps in a section named
GLIBCXX_3.4, the same section libstdc++ weakly exports it in.)

Note that LibreOffice now moved away from version scripts, so we don't have
this particular problem in LibreOffice anymore.

I find another related issue from LibreOffice's past, see
http://www.sourceware.org/ml/binutils/2003-02/msg00055.html
Open/LibreOffice eventually standardised on something "UDK_3_0_0" for the
"Base" that is mentioned above, but I wonder how badly that interacted with
"external" C++ libraries that were using the anonymous _ZTI* and _ZTS* symbols.
/me thinks badly.

So, although LibreOffice does not suffer from these issues anymore, I guess
binutils should provide a solution.

I cannot anymore reproduce the abort as originally encountered with C++'s
std::string; it looks like std::string's destructor does not anymore rely on
unicity of the _S_empty_rep_storage symbol. This works around this problem.

>From my test-case, "make foo-ok" still fails, because mixing anonymous tags and
versioned tags is still forbidden. Comment 4 says it should be so, but then
immediately starts talking about "solaris platform", so:

1) I'm not sure if mixing anonymous tags and versioned tags should be forbidden
on other platforms, too.

2) I don't see how to solve the original problem, which was to use global
symbols THAT LD MUST MERGE with the same symbol in other libraries, in a
library that uses versioned symbols and hides its symbols by default, but
"unhides" specifically this global symbol. In other words: how to hide all
symbols, except one, and leave that "not hidden" symbol as if there was
absolutely no version script?

Maybe on most platforms we should allow mixing of anonymous and non-anonymous
tags, and on solaris only, automatically replace "anonymous" by "base version"?

anonymous tag may not be combined with other tags.

Instead, on Solaris platform, any non-tagged symbol must be tagged with "Base
version": soname or file base name (if no soname)

https://github.com/illumos/illumos-gate/blob/master/usr/src/cmd/sgs/libld/common/version.c#L948

So if libfoo.so.2 has such a mapfile:

{
global:
foo_hello;
foo_world;
}

it must be read as:

libfoo.so.2 {
global:
foo_hello;
foo_world;
}

What about assigning [on the fly] some tag instead to those "anonymous" tags?

Say "__solaris_anon" or whatsoever. Or maybe "Base". dpkg-gensymbols list
anonymous tags as @Base. In any case if this will be fixed in other way, we can
use LD_NOVERSION for transition.

I' not sure. I got "File format not recognized" when linking library built with
this patch (and mixing anon- and non-anon tags)
