Comment 1 Aron Budea 2017-07-25 22:18:32 UTC
Asserts are only evaluated in debug builds. I assume is a release build, right? (which would mean it's not sure whether this is a regression)

Reproduced in a 6.0 master dbgutil build in Windows 7.
Comment 2 Julien Nabet 2017-07-26 14:35:37 UTC
On pc Debian x86-64 with master sources updated today, I could reproduce this.

Here's main part of the bt:

Comment 3 Xisco Faulí 2017-07-26 14:37:46 UTC
I think it's not a debug build. I downloaded it yesterday from http://dev-builds.libreoffice.org/daily/master/win-x86%4039/
Comment 4 Julien Nabet 2017-07-26 15:11:43 UTC
Let's give it a try with https://gerrit.libreoffice.org/#/c/40456/
At least, I don't reproduce the assert with it.
Comment 5 Julien Nabet 2017-07-26 16:54:07 UTC
Xisco: don't hesitate to reopen this tracker if you still reproduce this after with a build including the patch.
