Steps to Reproduce and Observed Behavior

const print = @import("std").debug.print;

const DirEntry = extern struct {
    name:               [8] u8,
    ext:                [3] u8,    
};

pub fn main() !void {
    var data_buffer: [512]u8 align(2)= undefined;

    const dir_entry_list: []DirEntry = &data_buffer;
    
    print("dir entry: {s}", .{dir_entry_list[0].name});    
}

Build or run

zig build-exe scratchpad.zig

Compiler crashes:

fish: Job 1, 'zig build-exe scratchpad.zig' terminated by signal SIGSEGV (Address boundary error)

Expected Behavior

Program builds or compiler throws some error.

Only observed with align(2) or more. align(1) or removing align throws compiler errors as expected.
