`Segmentation fault(core dumped)` when using multiple threads

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

```
