What did you do?

0. Download Termux and open it, and install git by using apt install git.
1. Install golang by using apt install golang.
2. Install python by using apt install python.
3. Clone crash-record.
4. Go to the target folder (crash-record).
5. Execute command sh make.sh to make two dynamic libraries named c1.so and c2.so. If work as well, then you will see the following things.
   
6. Execute command python crasher.py to run the dynamic libraries.

Note that c1.so and c2.so is actually built from the same code but the code is from different folder.
And, c1.so and c2.so both have only export one function that named DO which the go code is as follows.

package main

import "C"
import (
	"runtime"
	"time"
)

func main() {}

//export DO
func DO() {
	s := 2
	s++

	go func() {
		timer := time.NewTicker(time.Second / 20)
		for {
			<-timer.C
			runtime.GC()
		}
	}()
}

So, by calling DO, then Go side will init a number 2 to s and add 1 to it (but s is not used), then start a new thread that do GC each 0.05s (nerver stop).

For Python side, they just calling the dynamic library, and the code is as follows.

import ctypes
import time

LIB1 = ctypes.cdll.LoadLibrary("./c1.so")
LIB2 = ctypes.cdll.LoadLibrary("./c2.so")


LIB1.DO.argtypes = []
LIB1.DO.restype = None
LIB2.DO.argtypes = []
LIB2.DO.restype = None

LIB1.DO()
LIB2.DO()
time.sleep(1)
print("OK")

What did you see happen?

Go side panic with internal error, such as SIGSEGV: segmentation violation, stopTheWorld: not stopped and bad sweepgen in refill.

Note these error is copied from android/amd64 device (Windows Subsystem for Android), but you can see the same result in my android/arm64(aarch64) mobile phone.

What did you expect to see?

After running python crasher.py, then the program will wait 1 second and print OK and exit.

It seems that #65050 mentioned the same thing, so let me close this issue safely.
