Sorry to reply to my own post but I have been playing with this all
day to figure out what is wrong. I have narrowed the problem down to
the merge method, but I am not sure how to fix it. Here are some test
cases. These all pass in ruby 1.9.1. The first one fails in MacRuby
trunk, but the other two pass.
h = Hash.new do |h, k|
12
end
h = h.merge({1 => 2})
assert_equal(h[1], 2)
assert_equal(h[:random], 12)
h = Hash.new do |h, k|
12
end
h.merge!({1 => 2})
assert_equal(h[1], 2)
assert_equal(h[:random], 12)
h = Hash.new do |h, k|
12
end
h.merge({1 => 2})
assert_equal(h[1], 12)
assert_equal(h[:random], 12)

Hello,
I have been trying to get cucumber working with MacRuby, and I have
run into a bug. I have tracked the source of it down to a block of
code in cucumber's code base[BLOCK 1]. I have condensed this down to
a much smaller example[BLOCK 2]. In ruby 1.9.1 the second block
results in 'yellow,bold', but in macruby the second block results in
nil.
My guess is that there is a bug in the merge implementation or the
constructor implementation. I am not familiar enough with ruby to
know which, so I will take a look at both. I feel this should be
added as a test case, but I am not sure where to put that, since I
am new to the project. Any tips?
