+Summary: [REGRESSION] PInvoking with CharSet.Auto causes assertion failure in runtime
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+PInvoking with CharSet.Auto causes assertion failure in runtime
+(though I'm not an expert of PInvoke and it is possible that Auto is just
+invalid here)
+
+Steps to reproduce the problem:
+1. Compile and run following program with mono svn
+
+using System;
+using System.Runtime.InteropServices;
+
+class NativeReadLine
+{
+  [DllImport ("readline", CharSet = CharSet.Auto)]
+  static extern string readline (string x);
+
+  public string ReadLine (string prompt) {
+    Console.WriteLine ("read line");
+    return readline (prompt);
+  }
+}
+
+class HacksFramework
+{
+  public static void Main () {
+    // libreadline is broken on my machine, we need to call something
+    // in libtermcap.so to initialize it properly
+    try { tgetnum (""); } catch {  }
+
+    NativeReadLine rl = new NativeReadLine ();
+    System.Console.WriteLine (rl.ReadLine ("bla"));
+  }
+  
+  // helper call for making system load needed libs
+  [DllImport ("termcap", CharSet = CharSet.Auto)]
+  static extern int tgetnum (string x);
+}
+
+
+Actual Results:
+** ERROR **: file marshal.c: line 1143 (conv_to_icall): should not be reached
+aborting...
+
+
+Expected Results:
+bla
+
+How often does this happen? 
+With mono svn always. With mono 1.1.8 it works fine.
