            Bug ID: 144513
           Summary: Perf: editengine hangs for *very* long time in
                    TextEngine::CreateLines when trying to display a long
                    line in a cell
           Product: LibreOffice
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium

Created attachment 175026

A sample file with a query to return a 140000-char string

The attachment is rather a corner case, to demonstrate the problem. It contains
a table in Firebird DB with 6-digit integers, and a query to combine them into
a single semicolon-delimited 140000-character string. Trying to execute the
query performs the SQL instantly, but then hangs ~forever in
TextEngine::CreateLines.

(So this is not a Base-related problem; I assume it would hit any such case,
and I seem to remember to also see it when testing Calc's cell data limit.)

Noel: possibly you could take a look and apply your magic here? :)
