    Work around strange -fsanitize=integer issue
    
    With clang 14, __attribute__ ((nosanitize)) stops working with
    
        -fsanitize=undefined,integer
    
    Using the following works (and should be equivalent)
    
        -fsanitize=undefined,unsigned-integer-overflow,implicit-conversion
