Steps to Reproduce and Observed Behavior

const std = @import("std");

pub fn main() !void {
    const segf = struct {
        pub fn format(self: @This(), _: anytype, _: anytype, writer: anytype) !void {
            try writer.print("{}", .{self});
        }
    };
    std.debug.print("{}", .{segf{}});
}

run zig run format.zig
result: segmentation fault (core dumped) zig run format.zig

Expected Behavior

some type of dependency loop compile error

Infinite recursion is not an error in Zig.
