Created attachment 200374 [details] forum-mso-de-131263.xlsx Open the attached file, forum-mso-de-131263.xlsx. => Calc hangs. Observed using LO 25.8.0.0.alpha0+ (22ef238e820955f6f8ac84781289b8a1d8e477b9), 3.3.0 / Windows. The sheet has lots of INDIRECT functions, which made me think it could be similar to bug 166167, but here a significant amount of time is spent in ScDiv and ScFind instead.
