Hi Jesus, We have looked at it with Pablo. We were wondering too if you could give us a reproducible case for what is not working with you, because we have tested it and it seems to be working (details below). The array replace primitive is a generic primitive that handles the replace of arrays of objects and arrays of native values (8, 16, 32, 64bit values). Now, for the primitive to work, both arrays should be of the same type/format. âAll these examples do use the primitive" a := WordArray withAll: #( 1 2 3 4 ). b := WordArray withAll: #( 5 6 ). a replaceFrom: 1 to: 2 with: b startingAt: 1. a := DoubleWordArray withAll: #( 1 2 3 4 ). b := DoubleWordArray withAll: #( 5 6 ). a replaceFrom: 1 to: 2 with: b startingAt: 1. âAll these examples do not use the primitive" a := DoubleWordArray withAll: #( 1 2 3 4 ). b := ByteArray withAll: #( 5 6 ). a replaceFrom: 1 to: 2 with: b startingAt: 1. a := DoubleWordArray withAll: #( 1 2 3 4 ). b := Array withAll: #( 5 6 ). a replaceFrom: 1 to: 2 with: b startingAt: 1. If you tell us a bit more we could probably be of more help. Also, we were looking for you in discord to ask you questions, are you there? Guille

Thanks for your response I've tried in WordArray and ByteArray and same behaviour, primitive 105 fails and executes the code after the primitive call. It is Pharo 8.0 64 on Mac Os X...I will try on Ubuntu 19.4...as soon as I can. the same problem in all of the Collection-Native all of them use primitive 105

I am developing a "numpy arrays" like framework on pharo,
Cool
I decided to use an Array type depending on the class of its elements (I thought it would be more efficient) i.e if the array contains floats it will be stored in a floatArray but if contains integers, a IntegerArray will be used.
Did you check the WordArray class and friend?
I make an extensive use of use of the method replaceFrom: start to: stop with: replacement startingAt: repStart when I do concat and other methods that imply copying but I've realize that primitive 105 is not executes when I call this method from these kind of arrays but it works if I use a normal Array. What do you suggest me to do? is it better to use the normal Array for every type of content or is it a bugg? Is FloatArray/IntegerArray more efficient in any way? If not...what is their purpose?
I read the code and I do not understand why this primitives have all the same number. May be this is normal. I will ask around.
replaceFrom: start to: stop with: replacement startingAt: repStart "Primitive. This destructively replaces elements from start to stop in the receiver starting at index, repStart, in the collection, replacement. Answer the receiver. Range checks are performed in the primitive only. Optional. See Object documentation whatIsAPrimitive." <primitive: 105> super replaceFrom: start to: stop with: replacement startingAt: repStart
