/* C / C++'s logical AND and OR operators take any scalar argument
which compares (un)equal to 0 - the result 1 or 0 and of type int.
In this testcase, the int result is again converted to a floating-poing
or complex type.
While having a floating-point/complex array element with || and && can make
sense, having a non-integer/non-bool reduction variable is odd but valid.
Test: FP reduction variable + FP array. */
