FWIW, I can reproduce this now on Solaris without any magic compiler switches:
The program is just this here:

foo(char *buf, int bufsz);

Well, it confirmed that void_list_node is not used, but I can't
reproduce this fact.
Then how should we go on with this? As said, I can also only

Can we use anything else to terminate the loop? Is there any other debug
output
that would be helpful for you?

Unfortunately I cannot confirm that this bug is fixed, so I need to reopen it.
For one thing this bug is not only about variadic functions, but
dump_function_declaration()

Compare it to:
typedef int mytype;
int myfunc2(mytype var) {
return 1;
};
which outputs
static int myfunc2 (mytype);

That could be related to the function pointer issue where
print_generic_decl()
also rather repeats the declaration instead of printing the new type.

print_generic_decl is designed for debugging reasons only. Any other use is a

Well I think you need to debug it to see why it is printing out static, it
might because a bit on tree has not been set yet.
