Attached a small project to observe the problem/test the patches. There
are two libraries inside:
- slash.lib contains one symbol with '/' in its LIB_ID
- slash_conflict.lib contains two symbols that result in a LIB_ID clash
(RELAY_Hongfa_HF115F/012-1H3T and RELAY_Hongfa_HF115F_012-1H3T).

Normally you can use slash.lib, but if you want to check what happens in
case of a conflict, then use the other one.
