            Bug ID: 57524
           Summary: internal compiler error on dump translation unit
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: JamesMikeDuPont at googlemail dot com

using the debian sid standard : GNU C++ (Debian 4.7.2-5) version 4.7.2
(x86_64-linux-gnu) compiled by GNU C version 4.7.2, GMP version 5.0.5, MPFR
version 3.1.0-p10, MPC version 0.9 warning: MPFR header version 3.1.0-p10
differs from library version 3.1.1-p2. GGC heuristics: --param

Compiling boost spirit.qi code,
Here is the one that creates the error.

Invocation is :
/usr/lib/gcc/x86_64-linux-gnu/4.7/cc1plus -std=gnu++11 -fdump-translation-unit
treedumpparse.ii

the output is:

(this is the last of the function print )
 std::size_t boost::detail::variant::variant_hasher::operator()(const T&) const

the error is :

Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.7/README.Bugs> for instructions.

This can be reproduced with this one include :
#include "/usr/include/boost/variant/detail/hash_variant.hpp"


I am trying to reduce the problem, but it is difficult.

--- Comment #1 from James Michael DuPont <JamesMikeDuPont at googlemail dot com> ---
I tried to reduce the input size but it is not producing any results.

namespace std {
  typedef long unsigned int size_t;    
};
namespace boost { 
  namespace detail {
    struct is_static_visitor_tag { };
    typedef void static_visitor_default_return;
  } 
  template <typename R = ::boost::detail::static_visitor_default_return>
  class static_visitor    : public detail::is_static_visitor_tag {
  public:
    typedef R result_type;
  protected:
    static_visitor() { }    ~static_visitor() { }
  };}
namespace boost
{
  template <class T> struct hash;
  template <class T> void hash_combine(std::size_t& seed, T const& v);
  template <class It> std::size_t hash_range(It, It);
  template <class It> void hash_range(std::size_t&, It, It);
}
namespace boost {
  namespace detail { namespace variant {
      struct variant_hasher: public boost::static_visitor<std::size_t> {
    template <class T>
    std::size_t operator()(T const& val) const {
      using namespace boost;
      hash<T> hasher;
      return hasher(val);
    }      };    }  }}

--- Comment #2 from James Michael DuPont <JamesMikeDuPont at googlemail dot com> ---
Here is a small change to work around the crash :

namespace boost {

    namespace detail { namespace variant {
        struct variant_hasher: public //boost::
    static_visitor<std::size_t> {
            template <class T>
            std::size_t operator()(T const& val) const {
          //using namespace boost;
                hash<T> hasher;
                return hasher(val);
            }
        };
    }}
}

It is the uneeded namespace usage that causes the problem.

Created attachment 30259
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=30259&action=edit
test case

this is the minimal test case that I have.
by applying the small namespace changes to the end it will go away.

I have filed a small cosmetic bug in boost about this change to the namespace

I can't reproduce the issue anywhere. Eg, not on stock FSF 4.7.2, not on 4.8 or
current mainline.

Can somebody reproduce?

This still happens with 4.9:

using namespace indirect_traits;
void fn1() {
using namespace detail;
}
}

markus@x4 more % g++ -ftime-report -c test.ii

As far as I can see, it's just matter of using timevar_cond_start instead of
timevar_start.
