Hi,

I have a C++ DLL which has exported functions which is used in a C#
application via DllImport. The C++ DLL is linked to various .lib files
which use boost functionality (thread, asio etc) internally and are
compiled with BOOST_ALL_DYN_LINK option to work with C++\CLI

When I run the application it just hangs with following stack trace. I get
the same results if I convert this to a C++\CLI DLL and use it directly
from the C# application.

Stack Trace:

------------------------------------------------

As it can be seen, it stops in start_thread inside win_thread.ipp at
following
lines on WaitForSingleObject

if (entry_event)
{
  ::WaitForSingleObject(entry_event, INFINITE);
  ::CloseHandle(entry_event);
}

I am just creating a timer object in the code and do not understand why it
leads
to this situation. Also everything works fine when I use a LIB instead of
DLL
and all code is in C++.

Environment details are as follows
OS: Win XP
IDE: Visual Studio 2010
Boost version: boost_1_48_0

Chaitanya
