Hello,

We found issue in IronRuby core when running on Windows Phone 7  
emulator.  
Below is the code to reproduce the issue:

def test(\*args);  
puts ‘test’;  
raise ArgumentError, ‘Error’;  
end;

begin;  
test;  
rescue =\> e;  
puts ‘caught’;  
end;"

The problem is that rescue does not called and exception goes throw.

If we change test to:  
def test();  
puts ‘test’;  
raise ArgumentError, ‘Error’;  
end;

Exception caught fine. So the issue is with variable parameters list

Does anybody has any idea why it may happen?

Regards,  
Evgeny.
