test/stack.go fails intermittently on arm5 #1750
Description
The linux-arm-arm5 dashboard build is unreliable, failing often during the src/all.bash build with "throw: all goroutines are asleep - deadlock!". This issue spawns from a discussion on golang-dev, http://groups.google.com/group/golang-dev/browse_thread/thread/66223a50df58a39c/07a6b34f183bd381?lnk=gst&;q=arm5+#07a6b34f183bd381 What is the expected output? Correct programs should not deadlock What do you see instead? throw: all goroutines are asleep - deadlock! Which compiler are you using (5g, 6g, 8g, gccgo)?
