CALLTRACE_RETURN() ends the trace before return value; which is expected after return #1
Description
Current Implementation: #define CALLTRACE_RETURN(...) do { CALLTRACE_END(); return VA_ARGS; } while(0)
Expected Implementation: #define CALLTRACE_RETURN(...) do { typeof(VA_ARGS) v = VA_ARGS; CALLTRACE_END(); return v; } while(0)
