Possible Mac issue

[obroadrick]

The following code works on my friend's linux machine but on my mac I get an error: "AssertionError: length(branches(bl)) == 2".

using Alea
macro bn()
return esc(quote
burglary = flip(0.001)
earthquake = flip(0.002)
if burglary && earthquake alarm = flip(0.95)
elseif burglary && !earthquake alarm = flip(0.94)
elseif !burglary && earthquake alarm = flip(0.29)
else alarm = flip(0.001) end
john_calls = if alarm flip(0.9) else flip(0.05) end
mary_calls = if alarm flip(0.7) else flip(0.01) end
end)
end
pa = @alea begin
@bn()
observe(john_calls && mary_calls)
return (burglary || earthquake)
end
pb = @alea begin
@bn()
observe(!burglary && mary_calls)
return earthquake
end
println("Pr(burglary || earthquake; john_calls && mary_calls) = $(pr(pa)[true])")
println("Pr(earthquake; !burglary && mary_calls) = $(pr(pb)[true])")

I get the same error on my Linux machine. I believe it is an issue in IRTools library. Thanks for pointing this out!
