I typoed the argument passed to getcontext in getTraceback, and the error was hidden by ucontext_arg. This would have been caught by some of the runtime package tests, but we don't run most of them because they rely on `go build`, and the go tool is not available while running the libgo testsuite. We should fix the libgo testsuite, somehow, so that they run. Reviewed-on: https://go-review.googlesource.com/35837 From-SVN: r244946
