Addresse a = getAddressFromString("12D5aJQQ7JsRdh42wdMwBFLYVLSFmh2RY2", ...)
if(a){
  Cluster c = cm.getCluster(a,...);
  auto addresses = c.getAddresses() | ranges::to_vector; <----- Crash here
}

Does this only happen with the mega cluster?

[ClementPavue]

I tried with other smaller clusters ( 1 millions addresses ) and the code above works yes

This should be fixed now with the latest v0.6, you'll need to re-run the clustering.

There was an issue where, if there were no addresses of type WITNESS_UNKNOWN, then during clustering addresses of type NONSTANDARD were serialized as WITNESS_UNKNOWN, leading to the crash when trying to reinstantiate these addresses.

Curiously, this only happened on Ubuntu, where a map was iterated over in a different order than on MacOS.
