Subject: [ruby-talk:8739] FloatDomainError exception, bug in Ruby?

Hi again!

Still using: "ruby 1.6.1 (2000-10-05) [i386-cygwin]"

This code:
---------------
begin
  # raises FloatDomainError
  f = 2.0
  loop {
   f *= f
   print f, "\n"
  }
rescue Exception
  print $!.type, " ", $@, "\n"
else
  print "No error raised.\n"
end
---------------

Does not work as expected (throwing FloatDomainError when f gets infinite).
The output (I had to break the program with Ctrl-C which raised the
Interrupt exception as expected):
---------------

16.0

Is this a bug?
