Ok, this patch definitely works. However, I think there is ways to get the

That is useful, yes. But it does not address this specific problem.
We need the function declaration remembered, rather than what we have
now -- a list of arguments with full type information, specific to its
callsite.
You cannot deduce that a function call is/not varargs presently, even
with a working pseudo->type setup.
varargs is just one of those annoying areas where the compiler needs to
have rather specific knowledge, in order to properly construct a call
