using std.debug.print() on struct function twice causes unreachable code in analyze.cpp

Zig Version

0.10.0-dev.2600+9360cfebc

Steps to Reproduce

I'm using the latest git commit as of right now, as I filled out in the version field, but it can also be reproduced on the Zig playground: https://zig-play.dev/

Minimal reproducible example:

const std = @import("std");

const St = struct {
    fn f() void {}
};

pub fn main() void {
    const st: St = undefined;
    std.debug.print("{}{}", .{st.f, st.f});
}

zig/src/stage1/analyze.cpp:7310 in const_values_equal. This is a bug in the Zig compiler.thread 31199 panic: 
Unable to dump stack trace: debug info stripped

This also causes the problem:

std.debug.print("{}", .{st.f});
std.debug.print("{}", .{st.f});

Printing once does not, and just outputs a normal compiler error as expected:

std.debug.print("{}", .{st.f});

/usr/lib/zig/std/fmt.zig:679:17: error: Unable to format type '(bound fn() void)'
        else => @compileError("Unable to format type '" ++ @typeName(T) ++ "'"),
                ^

Expected Behavior

The expected behavior is to output a normal and descriptive compiler error which shows the problem line.

Actual Behavior

The compiler reaches code marked unreachable in const_values_equal and crashes.
