Can someone try reproducing this for me. When I run the following program it
hangs _before_ entering the function doing a certain P/Invoke call. If I
comment out the sdp_list_append call it runs to completion. It doesn't occur
when run on the Windows mono.exe, but does in the Mono Suse vmx. It needs
BlueZ's libbluetooth.
My best guess is that the jitter is getting stuck? There may well be something
wrong with the P/Invoke definitions :-,), but I'm reporting the hang.
using System;
using System.Runtime.InteropServices;
class Foo2
{
static void Main()
{
Console.WriteLine("entering Main");
fn1();
}
static void fn1()
{
Console.WriteLine("entering fn1");
fn2();
}
static void fn2()
{
Console.WriteLine("entering fn2");
fn3();
}
static void fn3()
{
Console.WriteLine("entering fn3");
uuid_t svc_uuid = new uuid_t();
NativeMethods.sdp_uuid16_create(svc_uuid, 0x0100);
// With this call in place, the programs hangs apparently
// before entering this function. 'kill -QUIT' shows
// Main->fn1->fn2->fn2<0xffffffff>
// Comment it out and the program runs to completion
// (likely producing a memory error when it does so).
/**/
sdp_list_t search_list
= NativeMethods.sdp_list_append(null, svc_uuid);
//*/
}
[StructLayout(LayoutKind.Sequential)]
class uuid_t
{
public byte type;
public Guid uuid128; //?
}
[StructLayout(LayoutKind.Sequential)]
class sdp_list_t
{
public sdp_list_t next;
public IntPtr data;
}
class NativeMethods
{
const string BluetoothLibrary = "libbluetooth";
//sdp_list_t* sdp_list_append(sdp_list_t* list, void* d);
[DllImport(BluetoothLibrary)]
internal static extern sdp_list_t sdp_list_append(sdp_list_t list,
uuid_t d);

[DllImport(BluetoothLibrary)]
internal static extern uuid_t sdp_uuid16_create(uuid_t uuid, Int16
data);
}
}//class
The stack trace at hang is the following; note no fn3.
