If I select 4 sheets in a 19 sheet workbook, right click and select Delete Sheet... and then select YES, Calc crashes. I have no idea what the limits are, because if I manually delete all sheets singly until there are only 4 sheets left and then try to delete 2 simultaneously, they are deleted without a crash.
Update, I cannot consistently reproduce this problem, except on the original unchanged workbook. If I manually delete 14 sheets, and try to reproduce the problem using the resulting 5 sheet workbook, sometimes it crashes, sometimes it doesn't, even doing exactly the same thing on the same, unchanged 5 sheet workbook. I suspect the problem may have something to do with how Calc handles deleting worksheets when there are references to other workbooks or macros in the document, regardless of whether those references involve any of the sheets left in the workbook. So, there is clearly a bug, but it may have to remain until something reproducible shows up.
On which env are you? (Windows, Linux, MacOs) Could you give a try to last stable LO version 4.3.3?

Sorry, I apparently didn't get an email telling me there was a question. I am using Linux. At the time that I found the bug, I was running Mint Petra; however, having no use for a Linux that cannot but upgraded to a new distribution, I switched to Xubuntu. I think the problem occurred in the last LTS version of LO Calc before Version 4.4.2.2. Unfortunately, during the first few hours of trying LO Calc, I discovered (MOD() and DATE()) bugs that result in random incorrect answers caused by improper handling of significant digits. When I reported them, I was informed that these functions require the user to make sure the input to the functions are of a specific format, and that they are therefore not bugs. This means that I must read about the limitations of every function use and keep notes I can refer to every time I want to use a function. Since computers are supposed to work for users, and not users for computers, this is unacceptable. In addition, in certain professions, random incorrect answers are worse than crashes or not having the functions at all, because lives or property could be lost. For this reason, I see no reason to bother with LibreOffice Calc for serious work. Excel doesn't have these problems. Too bad everyone working on Linux wants to have their own version instead of making one version that works correctly. You might as well close this bug and wait for someone who is forced to use LibreOffice Calc to find it. I cannot afford to spend time helping programmers fix something that I can't use.
