Segmentation fault(core dumped) when using multiple threads

[wly2014]

I first make multiple copies of a PyObject, and then access them in multiple threads. Finally, I meet this error.
julia -t5

using PyCall

py"""
class A():
    x = 0.0
a = A()
"""

alist = [deepcopy(py"a") for i in 1:10]
# @show alist

for j in 1:100
    Threads.@threads for i in 1:10
        alist[i].x
    end
end
