When compiling libsepol tests, clang complains about some uninitialized
variables:
test-common.c:171:14: error: variable 'my_primary' is used
uninitialized whenever 'if' condition is false
[-Werror,-Wsometimes-uninitialized]
} else if (my_flavor == TYPE_ALIAS) {
^~~~~~~~~~~~~~~~~~~~~~~
test-common.c:179:30: note: uninitialized use occurs here
CU_ASSERT(type->primary == my_primary);
^~~~~~~~~~
/usr/include/CUnit/CUnit.h:123:30: note: expanded from macro
'CU_ASSERT'
{ CU_assertImplementation((value), __LINE__, #value, __FILE__, "", CU_...
^
test-common.c:171:10: note: remove the 'if' if its condition is
always true
} else if (my_flavor == TYPE_ALIAS) {
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
test-common.c:153:25: note: initialize the variable 'my_primary' to
silence this warning
unsigned int my_primary, my_flavor, my_value;
^
= 0
test-common.c:171:14: error: variable 'my_value' is used
uninitialized whenever 'if' condition is false
[-Werror,-Wsometimes-uninitialized]
} else if (my_flavor == TYPE_ALIAS) {
^~~~~~~~~~~~~~~~~~~~~~~
test-common.c:181:30: note: uninitialized use occurs here
CU_ASSERT(type->s.value == my_value);

This is because the call to CU_FAIL("not an alias") is not fatal in
test_alias_datum(), and variables my_primary and my_value are indeed
used uninitialized in a CU_ASSERT statement later.
Silent the warning by moving the elseif condition to a CU_ASSERT
statement which replaces the CU_FAIL.
