Segmentation Fault when calling a function within a call to printf

[dylanjtuttle]

When calling a function within a call to printf, we get a segmentation fault during the running of the generated assembly.

Minimum reproducible example:

func main() returns void {
    printf("{}", return1());
}

func return1() returns int {
    return 1;
}

This is likely caused by the stack frames created and destroyed over the course of a subroutine messing with the stack offsets of the arguments being passed into printf, which are extremely finicky.
