could not open /system/bin/run-as

[zdzicho0]

Code generating info:

	int f=open(argv[1],O_RDONLY);
	if (f == -1) {
		LOGV("could not open %s", argv[1]);
		return 0;
	}
	if (fstat(f,&st) == -1) {
		LOGV("could not open %s", argv[1]);
		return 0;
	}

Do You know what can be the reason ?

shell@m0:/system/bin $ ls -l run-as
-rwxr-x--- root     shell        9432 2014-01-25 09:03 run-as

Very strange. Perhaps you can try pull the latest and run make test. You will at least know whether your device is vulnerable.
