RF2 server crashing after custom plugin update

Hi everybody. I created a custom server-side plugin thas has been working for more than 1 year. I made some changes in the code, compiled it and moved it to my test server in a Windows 2008 VM. Now, everytime I try to start the server, it dies with no error message. Enabled RF2 trace, but got no error on it. Had a look at Windows Event Viewer, no error. It's obviously a problem with my code update, because server starts if I remove the plugin.
I'm completely lost as I don't know how to get more info about this crash. Can you please help me?

 

Can you compile in debug mode and attach the debugger to the process before it crashes?

 

RF2 server process is alive for less than 1 second. Could I attach the debugger into it?

 

Throw in output messages (close file each time to flush buffers) through the startup code and see where it stops. Insert new messages, repeat.
