fft error

[staticfloat]

When running test/fft.jl, I get the following error:

ERROR: assertion failed: |:(rfftn_m4[i,j]) - :(true_fftn_m4[i,j])| < 2.3364326363345896e-10
  :(rfftn_m4[i,j]) = -13.0 + 2.0im
  :(true_fftn_m4[i,j]) = 0.0 + 0.0im

Running Julia manually, and recreating rfftn_m4 I get:

3x4 Complex128 Array:
 136.0+0.0im  -13.0+2.0im  -4.0+1.0im                    4.0-7.0im
   0.0+0.0im  -6.0-11.0im   4.0+9.0im  6.93094e-310+6.93094e-310im
   0.0+0.0im   19.0+8.0im  -4.0+1.0im  6.93094e-310+6.93094e-310im

EDIT: Just confirmed that this occurs on Linux as well
