Hello,
we just recently switched from FixInsight 2019.01upd1 to latest version 2021.10 and also observed this.
As Roman mentioned earlier, we found out that we now need to pass Delphi's sources path (e.g. C:\Program Files (x86)\Embarcadero\Studio\21.0\source ) as --libpath to FixInsightCL.exe.
Also --unitscopes should be given.
For further details, find the duplicate topic that we opened, here: FixInsight 2021.10 CL detects fewer issues than its IDE expert
Best regards,
Thorsten Schroff
