Replication: Create and save two empty docs. In the 1st doc, insert a section and 'link' its contents to the 2nd doc. Save the 1st doc. In the 2nd doc, 'insert' a 'section', set 'link' checkbox, set 'file name' to the 1st doc. After clicking 'Insert', Writer freezes with maximum cpu usage. Expected result: Writer recognises the attempt to back-link and -- this is just an idea -- blocks the 'links update' functionality for the offending content, with an informational message. But surely not use up all the resources.

Well, this is a "deadlock". > this is just an idea -- blocks the 'links update' functionality > for the offending content, with an informational message. Good idead! So you can propose a patch to fix.

Was able to recreate this issue today with Yury's steps. Windows 7 and 4.2.0

Created attachment 86679 [details] Screenshot showing OpenOffice CPU usage upon circular reference freeze I have been able to replicate the issue as described on MacOS 10.14.4 and OpenOffice AOO416m1(Build:9790), Rev. 1844436, however, I have also seen a related issue where Writer actually crashes if both documents are open when the circular reference is inserted. See below. Replication steps: 1. Create new Writer document. 2. Save to disk as e.g. Doc01.odt. 3. Create another new Writer document. 4. Save to disk as e.g. Doc02.odt. 5. Return to/open the first document. 6. Insert > Section... 7. Check the 'Link' checkbox and use the browse feature to select the second document. 8. Save then close the first document. 9. Open the second document. 10. Insert > Section... 11. Check the 'Link' checkbox and use the browse feature to select the first document. 12. Click 'Insert'. At this point by monitoring OpenOffice in MacOS Activity Monitor I saw the CPU usage increase dramatically and Writer become unresponsive (see attached screenshot). Memory usage also began to increase exponentially. I also attempted to alternative steps where I did not close the first document at step 8. On my OS (see configuration details below), this resulted in a crash of OpenOffice instead of OO becoming unresponsive and consuming more resources. I will attach the crash report as a second comment. (After the program crash or force quit, OpenOffice offered to recover the document(s) and did so successfully.) Configuration: macOS 10.14.4 (18E227) Model Identifier: MacBookPro15,2 Processor Name: Intel Core i7 Processor Speed: 2.7 GHz RAM: 16GB OpenOffice Version: AOO416m1(Build:9790) - Rev. 1844436 2018-10-22 14:11:36 (Mon, 22 Oct 2018) - Darwin x86_64
