Bug #4492

Updated by nobu (Nobuyoshi Nakada) over 11 years ago

=begin 
 On a Mac, this snippet crashes Ruby: 

  def 

 (({def f(*x); end 
  
 begin 
    
   f(*(0..120000)) 
  
 rescue 
    
   nil 
  
 end 
  f(*(0..120000)) 
 f(*(0..120000))})) 

 Here is the result when run with ruby: 

  segfaulter.rb:7:
