@phi-bee , Thanks for the review. 
I have added a commit addressing the concerns: 
- Folded the firstprivate/lastprivate pair check into WithMultipleAppearancesOmpException(..., prevFlag) and removed the separate helper. 
- The common-block member loop now uses that single call with FindObjectWithDSAByUltimate(member) when a prior clause recorded DSA on a different Symbol*  
- I kept ultimate-based lookup scoped to this helper rather than extending FindSymbolWithDSA() globally, since that function is also used by OpenACC and other paths and changing it caused CI failures when I tried that approach earlier.
