Hi Tom Tromey,

Thanks for looking into this.

Please find the steps:
1) Create a directory named TEST
2) In TEST create 2 GO files, test.go and export.go

=3D=3D=3D>test.go

package main

/*
#include <stdio.h>

extern void Test4(void);

void test1(void) {
   Test4();
}

void test2(void) {
    int val =3D 2;
    test1();
}

void test3(void) {
    int val =3D 3;
    test2();
}
*/
import "C"

func main() {
    C.test3()
}

=3D=3D=3D>export.go

package main

import "C"

//export Test4
func Test4() {
    panic("Panic inside Test4")
}

3) Run "go mod init test"
4) Run "go mod tidy"
5) Run "go build ."
6) Run "sudo su"
7) Run "ulimit -c unlimited"
8) Run "echo "core" > /proc/sys/kernel/core_pattern"
9) Run "GOTRACEBACK=3Dcrash ./test"
10) Run "gdb ./test core.243539"

Best Regards
Mariappan
