The problem is seen in many combination primary ion/target. Practically any macro-file prepared in the test can be used.
The test is verification/hadronic/IAEAion
Gunter (to whom this bug is assigned to) said that this bug is a report of a rare warning message from Binary Light Ion cascade on an internal problem by Vladimir Ivantchenko. We ask to report this warning if this occurs frequently. Vladimir reported 3 warnings for > 180k events. Some corrections were done for 10.0. Gunter needs to check with Vladimir if these warnings disappear. Gunter suggests to keep this open until Vladimir confirms that the warning no longer appears.
This problem was caused by a rare case of the spectator nucleus destroyed, i.e. all nucleons of the spectator nucleus had an interaction. In this case there was an inconsistant handling of the spectator nucleons, causing this warning. This has been corrected in Geant4 10.1.
Fixed in Geant4.10.1
