Compiling static recursive functions fails with "internal error: runOnce action depends on itself"

[albel727]

The following is literally enough to trigger the error:

static void kill(void) {
    kill();
}
void main(void) {
    kill();
}

Just removing the static qualifier produces the expected result.
Not calling kill() function from non-static functions such as main() also helps, but of course then kill() is not translated to rust at all.
Ping-pong style recursion works as long as one of the functions in the cycle is not static, i.e. the following works.

static void kill2(void);

void kill1(void) {
    kill2();
}

static void kill2(void) {
    kill1();
}

void main(void) {
    kill2();
}

I'm attempting to translate tree.c and I'd prefer this were a warning rather than an error.

This happens even when a function is not called.

static a() { a; }
b() { a; }
