Summary: SIGABRT wrapping delegate
Product: Mono: Runtime
Version: SVN
Platform: x86
OS/Version: Ubuntu
Status: NEW
Severity: Normal
Priority: P5 - None
Component: misc
AssignedTo: mono-bugs at ximian.com
ReportedBy: gert.driesen at pandora.be

While attempting to create a small repro for bug #342505, I got to a situation
where the code "should" result in the same error. However, the error differs
from the error reported from running NPlot.
To reproduce, compile and run the following code:
using System;
public class PlotMenuItem
{
private EventHandler callback_;
public PlotMenuItem ()
{
}
public PlotMenuItem (EventHandler callback)
{
callback_ = callback;
PlotMenuItem child = new PlotMenuItem ();
child.Callback += new EventHandler (callback);
}
static void Main ()
{
new PlotMenuItem (new EventHandler (MenuItem_Click));
}
static void MenuItem_Click (object sender, EventArgs e)
{
}
public EventHandler Callback {
get { return callback_; }
set { callback_ = value; }
}
}
Expected result:
Successful execution.
Actual result:
** ERROR **: file object.c: line 2089 (mono_object_get_virtual_method):
assertion failed: (res)
aborting...

Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
