Dapper looses parameters #1169

In some rare cases Dapper sends requests to SQLServer without parameters. I was able to reproduce it in test project:
https://github.com/dj-raphael/Dapper-test-lost-parameters

To reproduce, you should start this project in Visual Studio in Debug mode and wait for about a minute. However we encounter this problem from time to time (very rarely) in Release build on our production server. Here is the screenshot of exception we get:

Here is the log obtained using MiniProfiler.Integrations library, I'm logging sql request before it was sent to SQLServer

try
{
    ...
    var result = await connection.QueryAsync(sql.ToString(), map: Map, types: types, splitOn: splitOn, param: parameterValues).ConfigureAwait(false);
}
catch (SqlException e)
{
    e.Data["profile-query-after-dapper"] = profiler.GetCommands();
    e.AppendExceptionData(sql.ToString(), parameterValues);
    throw;
}

Log shows that I'm passing parameters to Dapper but SQLServer receives a request without any parameters at all. Another interesting fact is that it happens only when at least one of parameters is an array.
