I tried but it did not work. In fact, whenever you trhow any kind of 
exceptions (i.e. and int) the program crashes. And is not a \\\"Program 
Aborted\\\" message but a \\\"Segmentation Fault\\\".

I dont know what to do. I finally thought that it was a program 
related with my compiler, but I upgraded and tested code that uses 
exceptions and worked right. 

I will try to isolate the code I need, to see if it was a problem of 
the thread library or something... dont really know.

So if any of you have an idea... 

Thanks in advance (or however it is said) , Jose Fernandez.
