Hi,  
I have a project in which (somewhere) a Complex object is created which  
is not exactly performance-wise or desirable. Unfortunatly the project  
is fairly large and I have absolutely no idea where it is being created.  
Is there a way to trace the object creation to find where the Complex is  
object is created and initialized?

Thanks,  
Steven D.

See #set\_trace\_func. That may help.

WTF? Is this PEBCAK or server error?

Google Server Error. ruby-talk-google (the google group archive) is  
acting up. comp.lang.ruby is working okay though.

Thank you, I figured it out. Math.cos calls the Complex class.
