Crash with signal (4): Illegal instruction

[tknopp]

Hi,

this is a bug report that has been originally been filed against the NFFT package JuliaMath/NFFT.jl#29
but this might be a bug in Julia itself. The code to reproduce is:

using NFFT

struct container
  fourier_transform::NFFTPlan
end

function crash(x::Array{Complex{Float64},2}, cont::container)
  result = nfft(cont.fourier_transform, x) 
  return result
end

samples = rand(Float64, 2, 1000)
cont = container(NFFTPlan(samples, (64,64)))
x = rand(Complex{Float64}, 64,64)
crash(x, cont)

The interesting bit is that it does not crash if the NFFTPlan is not put into the struct. The error that I get is:

Unreachable reached at 0x12489fc42

This is probably the same issue as #29208 .
