Description: After every start of LibreOffice, you can define exactly one name with ' using the name box (not the dialog "Define names") e.g. a' but when you then put =a' into a cell it says Err:509 (Operator missing). You can only do this in the name box until you open the dialog "Define names". Steps to Reproduce: 1. close and start LibreOffice 2. in Calc's name box, type a' and press Enter Actual Results: name is accepted Expected Results: error message, name not accepted Reproducible: Always User Profile Reset: No Additional Info: the same in 5.3.1.2 User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:52.0) Gecko/20100101 Firefox/52.0
At least in master it is no longer possible to define these names. See e.g. https://cgit.freedesktop.org/libreoffice/core/commit/?id=a070d0d34763c83b4e957a7aee8b7f255a1d5519 that tests that test' is not a valid name and will not be accepted.
Most likely a duplicate of Bug 86214. The fix for that bug can not be backported as it changes translatable strings.
