    Issue #8649: fix "incompatible pointer to integer conversion".
    
    Since Clang 15.0.0:
    
    > The -Wint-conversion warning diagnostic for implicit int <-> pointer
    > conversions now defaults to an error in all C language modes. It may be
    > downgraded to a warning with -Wno-error=int-conversion, or disabled entirely
    > with -Wno-int-conversion.
