The following program hangs:

import core.atomic;

void main() {
    float num1 = 1;
    float num2 = 1;
    atomicOp!"+="(num1, num2);
}

If I change the operation to any other arithmetic operation, or change the
floats to doubles, it still hangs.  If I change num1 and num2 to ints or longs,
it works.
