policydb.c: In function ‘user_read’:
policydb.c:1443:26: error: ‘buf[2]’ may be used uninitialized in this function
[-Werror=maybe-uninitialized]
usrdatum->bounds = le32_to_cpu(buf[2]);
^
cc1: all warnings being treated as errors
Which makes no sense, as :
1). A couple of lines above it is being filled (buf[2]).
2). There are other instances of this which are not triggering this
failure.
But GCC insists, and this patch stops the failures.
