This error occurs when building with gcc 4.9. It has been fixed in dolphin git.

It builds fine for me with gcc 4.8 (although I get a linking error that I haven't figured out).

[Comment 4 Devan Franchini (RETIRED) 2015-03-12 21:18:51 UTC]

The best solution I can provide is to not compile dolphin-4.0.2 with GCC 4.9+ as stated previously. Or compile the dolphin-9999 version instead but please remember that this version is always up to date with the latest git HEAD of their repo.
