Not reproduce with LUbuntu 17.04 x64 and AOO 4.1.5

Did you think to reset the user profile before?

As I wrote above, this crash happens in Ubuntu 18.04.

I can confirm this problem with an old user profile under Debian Testing (Buster).

It works under a fresh Debian Stable (Stretch) with a free user profile.

To remove my user profile is no option now

Crash confirmed with AOO 4.1.5 under Ubuntu 18.04.1 x64
This was tested on a new user profile.

I could reproduce the crash on Xubuntu 18.04.1.

Ubuntu switched from FreeType 2.6.x in 16.04 to 2.8.x in 18.04.

The only occurrences searching for "FT_Glyph_Get_CBox" are in:
https://svn.apache.org/repos/asf/openoffice/trunk/main/vcl/source/glyphs/gcach_ftyp.cxx

After installing FreeType 2.8.1 via PPA on Ubuntu 16.04 the crash can be reproduced immediately with Jim's latest 4.1.6 build.

So I am asking for release blocker 4.1.6.

I think this bug will delay the release longer. I rather would like to release now and evaluate this again in the next release. Even a version 4.1.7 sounds more attractive then press this in 4.1.6.
I am sorry, but the initiative is welcome.

Also this might be older and not a new effect. I had crashes like this in 2017. But I forgot about it bcause of FOSDEM.

No, this crash is related to FreeType 2.8.x.

4.1.6 is likely to crash on every Linux that uses it.
4.1.5 crashes and even 4.2.0 does...

That will create a huge amount of traffic in the forum and on the list.

If we can fix it fast I change my mind. No patch no release blocker. Only exception: if a release can be blocked by the issue.
We can prepare another release if needed.

Maybe now that the problem is localized a developer could have a look at it?

We always released OpenOffice "when it is ready".

No problem with AOO 4.1.5 and freetype 2.3 on 32-bit CentOS 6.10. I can select master pages in sidebar without issue.

Of course not!

This issue is about Ubuntu 18.04 (and flavors) or Debian which uses FreeType 2.8.x.

Why was this set to unconfirmed?

The title says it all...

I checked now. Freetype 2.8.1 has been active since 2017-05-13 on arch. So I have the crash longer then that. I had use paste &copy for my talk on Fosdem 2017 because it crashed.
I thought it was special to Arch, so I thought if I build a special Version it will fix.

That fits to Mechtilde's comment.

Debian Stretch uses FreeType 2.6.x
Debian Buster uses Freetype 2.8.x

Crash occurs in Debian Buster.
And Ubuntu 18.04 is (more or less) based on Debian Buster.

AOO also crashes when accessing the master pages via menu:
View -> Master -> Slide Master
View -> Master -> Notes Master

side note: Draw does not crash when masterpage is opened.

I checked the code around FT_Glyph_Get_CBox() by a dry run.
It looks fine to me and there is no indication of a change in the freetype.
So my guess is that we have an ABI error.
Lets try to compile OpenOffice as is against freetype 2.8.x and see if that fixes the crash. If so we have an Issue with our distribution approach.

Possible patch on the report 127929. Lets continue there.
