Perhaps it's a problem of boost.mpl?

My Mingw 4.5 tests have the same error. e.g.

​http://tinyurl.com/y8uhc2r

however, the same error occurs in loads of Boost libs and only started happening last week so i'm not sure if it's a Boost bug of a GCC regression.

In either case, i think it's more of an MPL problem than a multi_index problem.

[Joaquín M López Muñoz]

The problem is affecting MPL, see for instance ​http://tinyurl.com/ybpm9m7 , so I'm transferring the ticket to that lib.

This seems to be fixed on Trunk now (all the multi_index tests are passing at any rate).
