--- Comment #25 from Patrick Luby (volunteer) <guibomac...@gmail.com> --- (In reply to Patrick Luby (volunteer) from comment #24) > Created attachment 195212 [details] > CPU Profile during hang using Xcode's Instruments application I obtained the CPU Profile in attachment #195212 by opening attachment #178982 and doing the following steps: - Select the "INDEX(MATCH)" sheet - Scroll down to row 150 and select only the filled cells in that row - Drag the "fill" rectangle in the bottom right corner of the selected cells down at least 100 rows >From the CPU Profile, it appears that most of the CPU time is being spent in various "mdds" functions within ScMatrixImpl::ExecuteBinaryOp(). If I repeat the above steps but if I first delete all of the formula cells in row 150 that contain an INDEX() formula, there is no hang. But, if I undo the cell deletions, the same hang occurs. I admit that I am not familiar with the code that handles range formulas such as the INDEX() formula so it is not clear to me what is going on during the hang. -- You are receiving this mail because: You are the assignee for the bug.
