a selfmade german-oldnorse dictionary from an internet source

when i am working with large and complex documents, writer usually freezes. it happens every time i am working with some documents, so writer nearly became usless for me.

this happens with virtually every little step, like deleting a letter.

it just recently happened - in a different document - that i wanted to delete all "sections" of a document an froze again

libre office freezing after going to page 4/220

See the video I made with 6.1 freezing just when at page 4/220. Not changeing anything...

Comment 2 Jean-Baptiste Faure 2018-08-21 09:22:09 UTC
Confirmed with LibreOffice 6.1.1.0.0+ built at home under Ubuntu 18.04 x86-64.

Set status to NEW.

Best regards. JBF

Repro with
Version: 6.2.0.0.alpha0+
Build ID: 414ef6cb187dd3bbcc917dbedf3c0c1cc8668f60

TinderBox: Win-x86@42, Branch:master, Time: 2018-08-20_22:43:18

it's initially working better with
Versie: 4.4.7.2 
Build ID: f3153a8b245191196a4b6b9abd1d0da16eead600
Locale: nl_NL

However eventually it will hang (consuming all resources) after a minute or so

No repro with as far I can tell (except with the spell checker enabled)
Versie 4.0.0.3 (Bouw-id: 7545bee9c2a0782548772a21bc84a9dcc583b89)
Comment 4 Telesto 2018-08-22 10:10:29 UTC
This should be bibisectable (with spell-checker disabled) assuming:
* my comment 3 about 4.0.0.3 is right 
* and with Linux also affected
Comment 5 Xisco Faulí 2018-08-22 13:19:16 UTC
I tried 3 times to bisect this issue but the results weren't correct...
If someone wants to try, I tried with bibisect-50max cleaning the user profile every time with rm -rf opt/user/.
I followed these steps:
1. Load the document
2. Wait until the word count reaches ~250.000.
3. Scroll down with the page down key...

But that was known already :) Like Xisco said, the bibisecting should be attempted with bibisect-50max

Not totally convinced about the 50max repro (but surely no need to check 5.4). I could reproduce the issue with "oldest" in bibisect-50max. By scrolling up & down the document randomly.. (last page, first page etc)

It's a nasty bug to bibisected, because it's harder to trigger the "layout loop" with older version.

It got stuck upon opening with gdb. Killed process and this is the result.
