[Bug c++/40055] New: Failing instantiation of template with enums

[alexandre dot hamez at gmail dot com]

The  following code failed with the message (no options are given to the
compiler): 

instance.cc: In function 'int main()':
instance.cc:30: error: no matching function for call to 'c_structa_tags,
a_struct::c_struct(a0_type)'
instance.cc:14: note: candidates are: c_structa_tags,
a_struct::c_struct(const c_structa_tags, a_struct)

---

enum a_tags { A0, A1 };
enum b_tags { B0, B1 };

template  a_tags Tag 
struct a_struct
{};

template  b_tags Tag 
struct b_struct
{};

template  typename tags, template  tags  class Element 
struct c_struct
{
  template  tags Tag 
  c_struct(Element Tag )
  {}
};

typedef c_struct a_tags, a_struct  a_type;
typedef c_struct b_tags, b_struct  b_type;
typedef a_struct A0  a0_type;
typedef b_struct B0  b0_type;

int main()
{
  a0_type a0;
  b0_type b0;
  b_type b_instance(b0);
  a_type a_instance(a0);
}

--

But if one of the line:
b_type b_instance(b0);
a_type a_instance(a0);
is commented out, then the compilation succeeds.

My g++ version, although I've been able to reproduce this bug with older
versions of gcc:
% /usr/local/env/gcc-4.4.0/bin/g++ -v 
Using built-in specs.

--disable-nls --enable-languages=c,c++
Thread model: posix
gcc version 4.4.0 (GCC)

I don't how to attach the preprocessed source. The file weight more than 1000k
so it is refused by bugzilla. And I think that copy-paste 56000 lines of code
is not the right thing to do?
At least, it seams that is is related to boost.
