LO 5.1 build broken

[Jean-Baptiste Faure]

Hi,

LO 5.1 is currently broken. I get the following error message:

> [build LOC] libreoffice
> [build LOC] top level modules: libreoffice
> /home/jbf/LibO/lo51/workdir/CxxObject/sc/source/ui/view/reffact.o: In function `ScValidationDlg::Close()':

My last successful build was incremental and for this buildID:
Version: 5.1.0.0.beta2+
Build ID: 8f63516df72b49e9347d90750f6d3ef3d4a1813f
Threads 4; Ver: 4.2; Render: default;
Ubuntu_15.10_x86-64
Locale : fr-FR (fr_FR.UTF-8)

Last night I did a complete rebuild (make distclean -> ./autogen.sh ->
make). I just changed optimization option from -O2 to -O3 for gcc
(version 5.2). What I do not undeerstand is why, when I reset my local
repository to commit 8f63516df72b49e9347d90750f6d3ef3d4a1813f, now I get
the same build error. Is it possible that the cause could be the change
I made for the optimization level?

Best regards.
JBF
