adding quadratic terms&constraints

Hi,
I'm running Julia 0.2.1 (64bit) on mac.
When I call test/qp_01.jl (also qp_02.jl), I got the following error message:

ERROR: access to undefined reference
in unsafe_copy! at array.jl:135

This was solved by changing the line 10 in src/cpx_quad.jl from
Q = Q + Q' - spdiagm(diag(Q))
to
Q = Q + Q' - spdiagm(convert(Array{Cdouble},diag(Q)))

It seems, when applied to a sparse matrix, diag returns an array of type ANY and this was causing the problem.

Hi @ywaki. Julia 0.2.1 is no longer being supported. Do you encounter the same issue on Julia 0.3.0?

Hi @mlubin, I just tried Julia 0.3.0, and it worked fine. Thanks!
