           Summary: [Preserve] attribute causes random code to execute
    Classification: Mono
           Product: MonoTouch
           Version: unspecified
          Platform: Macintosh
        OS/Version: Mac OS X 10.6
            Status: NEW
          Severity: Major
          Priority: P5 - None
         Component: Runtime

User-Agent:       Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64;
Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729;
Media Center PC 6.0; InfoPath.3)

Create a class:

public class MyItem
{
   [Preserve]
   public string MyParameter { get; set; }
}

Try to set the value by using generics and Reflection (actually using
SqlClient.cs) and calling

PropertyInfo p;

T obj = new T();
p = ...find parameter...
p.SetValue(obj, value, null);

Seems to randomly call a different object in the code tree, I think on the new
T().

Reproducible: Always

Steps to Reproduce:
1. As details
2.
3.
Actual Results:  
Should work normally.  Remove [Preserve] works fine
