error: Invalid record (Producer: 'zig 0.13.0' Reader: 'LLVM 18.1.8')

Zig Version

zig 0.13.0

Steps to Reproduce and Observed Behavior

const std = @import("std");

pub fn main() !void {
    std.debug.print("Test\n", .{});
    var line = "Hello world";
    const head: *const [3]u8 = line[0..3];
    try switch (head) {
        &[3]u8{'H', 'e', 'l'} => std.debug.print("Match!\n", .{}),
	else => error.hi,
    };
}

Compiling and running above yields:
$ zig run test.zig
error: Invalid record (Producer: 'zig 0.13.0' Reader: 'LLVM 18.1.8')

Expected Behavior

Since officially zig doesn't support switching on strings, I'd expect a compiler error instead of invalid LLVM bytecode.

Since officially zig doesn't support switching on strings

Technically your example is switching on a pointer (= an address), not its pointed-to array elements.
While this isn't used often, I do think it is intended to be supported (so I think your example is correct and it not compiling is indeed a bug).
