--- Comment #3 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
Thanks for filing this bug.
Reproduced on x86_64; looks like -fanalyzer's implementation of
BUILT_IN_VA_COPY makes assumptions about the types that don't hold for the
builtins created for x86_64 by ix86_init_builtins_va_builtins_abi (and
presumably something similar on aarch64?); am investigating.
