Sorry in advance for the long post. I have some trouble with a bug in one of my program. I was able to reproduce it with a simpler code, and it seems to be related to the Dict structure. I am not sure if the problem is coming from my code or from the structure itself in Base. FYI: Julia Version 0…

It seems to me it is the normal behaviour

Thank you for your answer. Are you sure it is normal for a value taken among the keys of a dictionary d that are in 1:8 to be equal 0? Am I missing something?

I am also puzzled by this. Here is a simpler MWE which visualizes the recursion: function mytest_inner(d::Dict{Int, Int}, i::Int, indent = 0) println_indent(indent, "popping $i from $d") pop!(d, i) println_indent(indent, "left with $d, keys $(keys(d))") for j in keys(d) # Problem is…

@Tamas_Papp Thank you for the simplification of the code and lisibility of the output. FYI, when I use this code in atom the KeyError corresponds to 0 in Atom REPL and to a big number (such as 140437488551752) in the Julia REPL. It looks like an access to wrong register (or the register has been e…

There is some problem with deepcopy in loop scope. Below f1 and f2 work OK, and f3 generates an error: function f1(d::Dict{Int, Int}, i::Int, indent = 0) pop!(d, i) z = deepcopy(d) for j in keys(d) # Problem is coming from here f1(z, j, indent + 1) end end function f2(d::Di…

@Azzaare : This looks like a bug. Perhaps you could open an issue.

I believe that the problem is in dict.jl: function Dict{K,V}(d::Dict{K,V}) where V where K if d.ndel > 0 rehash!(d) end @assert d.ndel == 0 new(copy(d.slots), copy(d.keys), copy(d.vals), 0, d.count, d.age, d.idxfloor, d.maxprobe) end w…

of course this is a hack and I believe a bug in dict.jl should be fixed.

I have already redeemed my Hacktoberfest tee. So @Azzaare , if you want go ahead and make a PR. If you do not have time I will do it - just let me know.

Is there a bug in `Dict`?
