Comment 2 Marek Polacek 2015-04-16 12:10:05 UTC 
Reproduced, even GCC mainline ICEs.  In fact, I think this is PR50800.
Comment 3 Marek Polacek 2015-04-16 12:41:36 UTC 
As a workaround, try not to use typedefs with may_alias (or similar attributes) as template parameters.
Comment 5 Dimitry Andric 2015-09-02 13:32:14 UTC 
(In reply to Marek Polacek from comment #3)
> As a workaround, try not to use typedefs with may_alias (or similar

The problem here is that such typedefs come straight out of boost-devel, e.g. on RHEL7 with boost-devel-1.53.0-23.el7.x86_64, the header /usr/include/boost/move/core.hpp has:

   //Move emulation rv breaks standard aliasing rules so add workarounds for some compilers
   #if defined(__GNUC__) && (__GNUC__ >= 4)
      #define BOOST_MOVE_ATTRIBUTE_MAY_ALIAS __attribute__((__may_alias__))
   #else
      #define BOOST_MOVE_ATTRIBUTE_MAY_ALIAS
   #endif

You can also see this in gcc PR50800, where the original submitter encounters the ICE when compiling something that includes boost:

   /home/gaunard/dev/boost/trunk/boost/type_traits/detail/cv_traits_impl.hpp:36:1: internal compiler error: in finish_member_declaration, at cp/semantics.c:2559

Note that this ICE also reproduces with gcc-c++-4.8.3-9.el7.x86_64, which is the default compiler in RHEL7.  So possibly many boost users are going to run into this.
Comment 10 Michael Petlan 2016-11-01 13:53:27 UTC 
Reproducible easily, verified with devtoolset-6-gcc-6.2.1-3.1.el{67}.

VERIFIED.
