Description
Hi, I get a runtime error, when errlog.Debug(...) is called multiple times in goroutine:
Error in main.routine: error 1
error in /home/vetti/projects/go/test-errlog/main.go (failing line not found, stack trace says func call is at line 12)
9: func routine(ch chan error, N int) {
10: for i := 0; i < N; i++ {
11: errlog.Debug(<-ch)
12: }
13: ch <- nil
Error: error 2
Errlog tried to debug the error but the stack trace seems empty. If you think this is an error, please open an issue at https://github.com/snwfdhmp/errlog/issues/new and provide us logs to investigate.

This code reproduces this problem (playground or version 2):
package main
import (
"errors"
"github.com/snwfdhmp/errlog"
)
func routine(ch chan error, N int) {
for i := 0; i < N; i++ {
errlog.Debug(<-ch)
}
ch <- nil
}
func main() {
ch := make(chan error)
go routine(ch, 3)
ch <- errors.New("error 1")
ch <- errors.New("error 2")
ch <- errors.New("error 3")
<-ch
}Why can this error occur?
