I placed some volumes using G4PVReplica. I used a width slightly larger than the width of the volumes placed therefore leaving a gap between them. Now, If I fire a particle in the gap and use /tracking/verbose the particle is said to go through the placed volume instead of its mother. If I place the volumes "by hand" with G4PVPlacement then I get the right result. I was describing my geometry using several layer of volumes placed with G4PVReplica (I think it's correct to place a volume with Replica in a volume already placed with Replica?) but it turned out that the tracking system says that the particle is in a volume instead of a gap (the mother). Worse, it seems to cause an infinite loop (see another report: infinite transportation).

As specified in section 3.6.4.2 of the User's Guide for Application Developers for 'Repeated volumes', it is not possible to add daughter volumes to replicated volumes if the size or type of solids varies (this actually needs to be generalised in the documentation to both parameterised volumes and replicas... thanks for pointing this out!). Doing so, will lead to unpredictable behavior. It looks like the specifications given to G4PVReplica in your geometry are not correct, since there cannot be 'gaps' inside a replica - a replica is a 'slicing' of the mother volume and the whole of the mother volume must be sliced. In case this diagnosis is not correct, please provide us a snippet of code with the geometry you defined so we can easily check and in case reproduce the problem.
