I have a cli application in Go (still in development) and no changes were made in source code neither on dependencies but all of a sudden it started to panic panic: sync: unlock of unlocked mutex
.
The only place I'm running concurrent code is to handle when program is requested to close:
func handleProcTermination() {
c := make(chan os.Signal, 1)
signal.Notify(c, os.Interrupt)
go func() {
<-c
curses.Endwin()
os.Exit(0)
}()
defer curses.Endwin()
}
Only thing I did was to rename my $GOPATH and work space folder. Can this operation cause such error?
Have some you experienced any related problem without having any explanation? Is there a rational check list that would help to find the cause of the problem?
