Tests fail when compiling with GCC 5.1 on Mac OS X

[felipou]

I just tried compiling and testing (make && make test) with the new GCC 5.1 on Mac OS X 10.10, but the tests resulted in many leak errors.

!!! WARNING The following tests failed:

There were errors on tests/unit as well as on tests/integration, all with .tcl files.

I'm not very familiar with the development of Redis (and even less so with tcl), so I couldn't understand the errors, but I thought it would be nice to report it. Is this kind of thing worth an issue here?
