The Travis build is segfaulting now because of this (but returns green anyway).

64 bit OS X:

julia> erf(complex(1.0))
0.8427007929497148 + 0.0im

32 bit Ubuntu:

julia> erf(complex(1.0))
Segmentation fault (core dumped)

For the specific example in this issue:

julia> erf(complex(1.0))
ERROR: MethodError: `erf` has no method matching erf(::Complex{Float64})
