String
can inadvertently touch libobjc when we implicitly cast it to a C string (when callinggetsectiondata()
), which can result in a deadlock if that operation needs to acquire one of libobjc's internal locks.Switch to
StaticString
which we can guarantee never touches libobjc.Resolves rdar://144093524.
