[Octave-bug-tracker] [bug #51565] Use nullptr rather than 0 in C++11 code

[Dmitri A. Sergatskov]

Follow-up Comment #7, bug #51565 (project octave):

I noticed that many of those warnings come from Qt headers.
So i compiled a minimal version with

../configure --disable-java --disable-docs --without-qt --without-fltk
CXXFLAGS="-g -O2 -Wzero-as-null-pointer-constant -Wno-noexcept-type
-Wno-implicit-fallthrough"


attached as gcc_min_err_20170726.log

Also attached the default build error log, gcc_err_20170726.log.bz2

Also noticed a new warning:
../libinterp/corefcn/pr-output.cc:1749:29: warning: ‘fw’ may be used
uninitialized in this function [-Wmaybe-uninitialized]
       int column_width = fw + 2;
                          ~~~^~~

Dmitri.
