panic when run multi goroutine

[TXYH1]

Hi，my environment is:
system: Ubuntu 18.04.5 LTS
golang: go1.14 linux/amd64
python version: Python 2.7.17

go code:

func init() {
	err := python.Initialize()
	if err != nil {
		panic(err.Error())
	}
}

func main(){
	m := python.PyImport_AddModule("sys")
	if m == nil {
		panic("fail to import module sys")
	}
	path := m.GetAttrString("path")
	if path == nil {
		panic("fail to get path")
	}

	curPath := python.PyString_FromString("/home/zjf/demopj/python")
	python.PyList_Insert(path, 0, curPath)
	m = python.PyImport_ImportModule("pyDemo")
	if m == nil {
		panic("fail to import module pyDemo")
	}

	func_abc := m.GetAttrString("print_abc")
	if func_abc == nil {
		panic("fail to get func_abc")
	}

	go func() {
		for {
			func_abc.CallFunction()
			time.Sleep(time.Millisecond)
		}
	}()

	go func() {
		for {
			func_abc.CallFunction()
			time.Sleep(time.Millisecond)
		}
	}()
	select {

	}
}

python code:

def print_abc():
    return "abc"

when run the go code, it panic stable, like:

Fatal Python error: GC object already tracked
or
fatal error: unexpected signal during runtime execution
[signal SIGSEGV: segmentation violation code=0x1 addr=0x58 pc=0x7fbec21f9da9]

Can you help me? Thank you very much.

presumably, that's the CPython's GIL showing its ugly head.
you need to serialize calls to the CPython interpreter.
