Comment 1 Halla Rempt 2020-05-14 07:44:01 UTC 
Which version of Qt are you building against?
Comment 2 grum999 2020-05-14 17:56:25 UTC 
(In reply to Boudewijn Rempt from comment #1)
> Which version of Qt are you building against?

I'm not sure to understand the question...

Qt 5.11.3 is installed on:
- building server
- testing server
(but the crash occurs on both servers)

Same information is retrieved on both machine from:
- Krita menu: "help > show system information for bug report" 
- Command line: "/usr/lib/x86_64-linux-gnu/qt5/bin/qmake --version"
Comment 3 Bug Janitor Service 2020-05-15 04:33:19 UTC 
Thanks for your comment!

Automatically switching the status of this bug to REPORTED so that the KDE team
knows that the bug is ready to get confirmed.

In the future you may also do this yourself when providing needed information.
Comment 4 Halla Rempt 2020-05-20 11:36:53 UTC 
Sorry, I missed that. Guess I need new glasses... I don't see a crash myself, but I have a different version of Qt and am working on a different distribution. 

I don't see anything in the backtraces that suggests a bug in Krita. Are you using special compiler flags to add ASAN or something like that?

Does a clean build/clean install from the krita/4.3 branch fix the issue for you?
Comment 5 Frans Slothouber 2020-07-01 07:58:24 UTC 
I have had the 'corrupted size vs. prev_size' crash too. 

This was solved by completely removing all files from install/,
removing  CMakeCache.txt from build/, and then doing a cmake ...  and make install.
Comment 6 Halla Rempt 2020-07-01 07:59:23 UTC 
Ah, then it is a build error.
