Wrong evaluation of default parameters

Project: JRuby
Issue Type: Bug

Affects Versions: JRuby 1.0.0RC2
Environment: fresh JRuby build, Linux
Reporter: Martin Krauskopf
Or at least different to MRI. Try the "known" trick to find out whether default
parameter was passed.
{code}
def m(a, b=(def_passed=true; 0))
puts "==="
puts " a: #{a}"
puts " b: #{b}"
puts " def_passed: #{def_passed.inspect}"
end
m(1)
m(1, 0)
m(1, 1)
{code}
