Building from source with Clang 15.0.6 on macOS (x86-64) yields the following
error:

./handler-macos.c:512:55: error: incompatible integer to pointer conversion
assigning to 'void *' from '__uint64_t
            ' (aka 'unsigned long long') [-Wint-conversion]
     161            new_esp -= sizeof (void *); *(void **)new_esp =
SIGSEGV_FRAME_POINTER (thread_state); /* push %rbp */

With Clang 15, this warning is now an error:
"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."
