2019-12-02libswcale: Fix possible string overflow in test.Adam Richter
In libswcale/tests/swcale.c, the function fileTest() calls sscanf in an argument of "%12s" on character srcStr[] and dstStr[], which are only 12 bytes. So, if the input string is 12 characters, a terminating null byte can be written past the end of these arrays. This bug was found by cppcheck.
