i found interesting bug. When you change culture of application while it's connected to firebird database, the connection won't be returned into pool.

Here is example code (from Page_Load) :
this.Culture = "en-GB";
FbConnection fbc = new FbConnection("Database=d:/database.fdb;DataSource=localhost;User=sysdba;Password=masterkey;Dialect=1;Charset=UTF8;Pooling=true;MinPoolSize=0;MaxPoolSize=10;Connection lifetime=30;");
fbc.Open();

    this\.Culture = "cs\-CZ";

// this.Culture = "en-GB"; When you change it back everything will be OK

    fbc\.Close\(\);

this code will fail after 10 calls on "System.InvalidOperationException: Connection pool is full". Its thrown from "FirebirdSql.Data.FirebirdClient.Pool.CreateNewConnectionIfPossibleImpl".

After quick look into the source code i think that problem is in generating NormalizedConnectionString (FbConnectgionString.cs:233). This code is probably culture dependent.

I'm using Fb .NET Provider version 4.1.0.0 and .NET FW version: 4.0.30319 and ASP .NET 4.0.30319.34009
