[Zig 0.15.2 Compiler Bug] server.zig:503 - parser reports expected EOF found }

[gHashTag]

Minimal Reproduction

const std = @import("std");
const Allocator = std.mem.Allocator;

pub const Response = struct {
    status: u16 = 200,
    content_type: []const u8 = "application/json",
    body: []const u8,
    cors: bool = true,
};

pub fn errorName(err: anyerror) []const u8 {
    return switch (err) {
        error.ConnectionFailed => "ConnectionFailed",
        error.InvalidResponse => "InvalidResponse",
        error.AuthFailed => "AuthFailed",
        error.GraphQL => "GraphQL",
        else => "Unknown",
    };
}

test "server: build health response" {
    const response = Response{
        .status = 200,
        .content_type = "application/json",
        .body = "{\"status\":\"ok\"}",
        .cors = true,
    };

    try std.testing.expect(response.status == 200);
    try std.testing.expectEqualStrings(response.body, "{\"status\":\"ok\"}");
}

Steps to Reproduce

1. zig test /path/to/file.zig
2. Observe: src/background_agent/server.zig:503:6: error: expected 'EOF', found '}'

Environment

• Zig version: 0.15.2 (Homebrew)
• OS: macOS Darwin 23.6.0
• Target: Debug native

Investigation Performed

• Hex dump shows no BOM or hidden characters
• Brace count: 149 open, 150 close (balanced)
• Test functions compile correctly in isolation
• zig fmt produces same error
• Fixing railway/client.zig line 34 did NOT resolve this error
• Error persists even after removing errorName function entirely

Expected Behavior

The syntax }; at line 503 should correctly close the errorName() function. The compiler incorrectly reports it as an error.

This appears to be a compiler parser bug in Zig 0.15.2.
