Description jclayton06 2019-10-18 20:09:59 UTC 
Description:
Performing (a basic) Regular Expression Find/Replace in Calc (e.g., "^NOT" --> "YES") causes a memory usage rise of ~3GB each time. Does not go away until closing the application.

Steps to Reproduce:
1.Insert ~50 rows of data
2.Find / Replace with "Match Case" and "Selected Text" and "Regular Expression" selected
3.Use a ^ starting regex and watch the magic.

Actual Results:
Memory leak and very unresponsive application until restart.

Expected Results:
No memory leak.


Reproducible: Always


User Profile Reset: No

Screenshot with memory usage in administrator.

Showing LibreOffice with Search/replace in shadow and memory usage in Task administrator.
Memory grows with subsequent searches but slowly. 
LibreOffice doesn't crash but became unusable, even close the file takes a lot.
