Am I using getResource incorrectly?

[Falconerd]

Hi there, thanks for making Zoltan!

I have been using Zoltan in my project but have come across an error under specific circumstances. I'm not entirely sure what the problem is, but I'll post a simple example that reproduces the issue (taken from the readme).

When the loop limit is 501, the code runs, when it's 502, there's an illegal instruction error.

const std = @import("std");
const Lua = @import("lua").Lua;
const assert = std.debug.assert;

pub fn main() !void {
    var lua = try Lua.init(std.testing.allocator);
    defer lua.destroy();

    lua.openLibs();

    var tbl = try lua.createTable();
    defer lua.release(tbl);

    lua.set("tbl", tbl);

    var inTbl = try lua.createTable();

    // Set, integer key
    inTbl.set(1, "string");
    inTbl.set(2, 3.1415);
    inTbl.set(3, 42);

    var tst1 = try inTbl.get([]const u8, 1);
    var tst2 = try inTbl.get(f32, 2);
    var tst3 = try inTbl.get(i32, 3);

    try std.testing.expect(std.mem.eql(u8, tst1, "string"));
    try std.testing.expect(tst2 == 3.1415);
    try std.testing.expect(tst3 == 42);

    // Set, string key
    inTbl.set("bool", true);

    var tst4 = try inTbl.get(bool, "bool");
    try std.testing.expect(tst4 == true);

    // Set table in parent
    tbl.set("inner", inTbl);
    // Now we can release the inTbl directly (tbl refers it)
    lua.release(inTbl);

    // Somewhere else, later.
    {
        var retTbl = try lua.getResource(Lua.Table, "tbl");
        defer lua.release(retTbl);

        var i: usize = 0;
        while (i < 502) : (i += 1) {
            var retInTbl = try retTbl.getResource(Lua.Table, "inner");
            lua.release(retInTbl);
        }
    }

    std.debug.print("Success.\n", .{});
}

The error:

While this example is contrived, I ran into this error in my project while looping through a sub-table.

Any help would be greatly appreciated!
