On some systems, the following won't compile because of the way the
macros are defined in the system headers:
va_copy(ap, va_listval(va_arg(ap, va_listarg)));
The error from clang is something like:
.../hashalloc.c:155:16: error: non-const lvalue reference to type
'__builtin_va_list' cannot bind to a temporary of type 'va_list'
(aka 'char *')
va_copy(ap, va_listval(va_arg(ap, va_listarg)));
~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
./ast_common.h:200:23: note: expanded from macro 'va_listval'
#define va_listval(p) (p)

.../include/stdarg.h:27:53: note: expanded from macro 'va_copy'
#define va_copy(dest, src) __builtin_va_copy(dest, src)

Thanks to Chase <nicetrynsa@protonmail.ch> for the bug report.

- Store va_listval() result in variable and pass that to va_copy().
