It's document 1 of the two

I don't seem to be able to upload document 2 as well.
Comment 2 Mike Kaganski 2020-02-22 14:30:17 UTC
Are the document 1 or the document 2 relevant? I suppose that what we need is the combined document that is failing?

Here's the odt document that crashes on attempted conversion to pdf

Please look at footnote 34 of the document just uploaded, containing two paragraphs. It's adding that content that makes the attached document crash when trying to convert it to pdf.

I should add that, if I just add the first paragraph of the footnote, the document converts properly. It's when I add the second paragraph that LO crashes.

I also tried to add the material as one paragraph, rather than two. When I add the first sentence only of paragraph two to the end of paragraph one, the document converts properly. However, when I add as well the second sentence of paragraph two to the end of paragraph one, I get the crash.

This can't have anything to do with exceeding some maximum length for footnote text, since the document has in it many footnotes longer than the one I'm trying to add.

I cannot reproduce a crash on Windows, but I see LibreOffice hang there.

Reproducible with Version: (x64)

and with OpenOffice.org 3.3.0 OOO330m20 (Build:9567).

@Julien, would it be possible to have a perf graph for this issue ?

Xisco: no problem but I got a crash for the moment following https://cgit.freedesktop.org/libreoffice/core/commit/?id=65404e2c72ea2d5d3f6c074121005b8b9369e7fb

Here's a Flamegraph retrieved on pc Debian x86-64 with master sources.

(I had to workaround the crash indicated in my previous comment).

Opening the file & copy/pasting the text to a new document solves the problem for some reason
