+++ This bug was initially created as a clone of Bug #605295 +++
-----
This bug is happening again on 2.10.6.
It causes the memory leak for bug #723148 I entered for GTK#.
The below test case indeed shows a memory leak in the identical situation: with
--debug it leaks, without it doesn't.
-----
This test case makes memory grow quickly. It works fine if the instance
delegate (cls.Run) is replaced by a delegate to a static method.
using System;
using System.Runtime.InteropServices;
namespace DelegateTest
{
class MainClass
{
public static void Main (string[] args)
{
MainClass cls = new MainClass ();
while (true) {
uint id = g_timeout_add (500, cls.Run, IntPtr.Zero);
g_source_remove (id);
}
}
bool Run ()
{
return false;
}
[DllImport("libglib-2.0.so")]
static extern void g_source_remove (uint id);
[DllImport("libglib-2.0.so")]
static extern uint g_timeout_add (uint id, Func<bool> function, IntPtr
data);
}
}
