Subject: Problem to embed Ruby in a threaded Application (Mingw)

Hello,

I have a problem with my application which embeds the Ruby engine.
I'll try to summarize the current status of my application :

I have a Qt4 Application which runs on Windows (thanks to Mingw).
In one thread created by this application, I would like to use the Ruby 1.8.2 
engine (to evaluate a script) [only in this thread which is created on the 
fly].

So, I create a thread which makes the following things :

- ruby_init
- rb_eval_string(my script) [encapsulated in a rb_protect mechanism]
- some rb_funcalls [encapsulated in a rb_protect mechanism]
- ruby_finalize

And the thread is finished (and destoyed).

So, the first time I run my thread, all is perfect.
But, the second time, a crash occurs in the rb_eval_string 
function. So, I suppose something wasn't correctly cleaned by 
ruby_finalize after the first thread execution...

Is there another way to finalize the Ruby engine ? Is something missing ?

Thank you

Frederic
