Symbol is perceived as different from libraries if contains pin with same number in V8

Schematic

If a symbol contains pins with the same number, the ERC and inspection->compare symbols
erroneously (?) mark the symbol as different from the library.

see for example this schematic attached of a 3 pin molex of our library:

In our library the mounting pins are called MP and have all the same ‘number’ (MP).
I think that is not correct to have the same pin number for pins that are physically different, so we are changing that.

You reckon the fact that this is ‘confusing’ the ERC may be is worth a gitlab issue?

Yes, a symbol with multiple pins with the same name is incorrect defined and should be corrected in the symbol editor.

Nevertheless the ERC result for this special case is at least misleading. There is already a open gitlab issue: Schematic ERC reports symbol changed in library for symbols with duplicate pins. (#17055) · Issues · KiCad / KiCad Source Code / kicad · GitLab
