--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Can you reproduce it with stage1 cc1plus?  As in, is it miscompiled compiler or
just some problem on the testcase?  If the former, can you bisect exactly to
the version and bisect which *.o file it is?

The test has not changed since Oct 23  2010.

I can do the bisection, but I don't understand what you mean by "*.o file it
is".

If stage1 fails, then it is not miscompilation of the compiler itself (or it
would be miscompilation by your system compiler instead).
So no *.o bisection is needed.  That said, I don't see what commit in that
range might be related.

My bootstrap compiler is

gcc version 5.0.0 20150107 (experimental) [trunk revision 219318] (GCC)

I don't know which compiler FX is using (I guess Clang).

Candidates are 219970, 219973, 219974, and 219981.

And indeed if I revert it, the ICE disappears.

Do you see the regression, with r219973 in place, if you bootstrap with gcc
4.9.2 rather than gcc 5.0svn? It also seems odd, if r219973 triggers this bug,
that you see it when bootstrapping with a gcc 5.0svn compiler built prior to
r219973.

??? 
Sorry,I don't understand what you are asking for: the ICE seems independent of
the bootstrap compiler (assuming FX is using clang).

My mistake, I thought FX wasn't showing the errors.

This seems to be because darwin_build_constant_cfstring uses CONST_DECL for a
global variable, and the C++ front end expects CONST_DECL to be used only for
enumerators.

Any ideas on how to recode that?

An error would be better than an ICE.

For the record, there are also several similar ICEs in the obj-c++ tests:

FAIL: obj-c++.dg/strings/const-str-5.mm -fnext-runtime (internal compiler
error)
