I tried the other configure command you suggested for a linux build and it failed on something different, but got past it on a second make command: It was building for a rather long time and I won't see if it fails or succeeds until Monday, but I'm interested in building it for Windows as well which fails. Using the windows configure and doing make -j4 -k and similar ended up eventually building everything except flex. I note a warning at the beginning of the build:
Warning - could not find native build version 4.3.0+ of octave - some packages may fail, but continuing 

Looking at log/build-flex I find warnings and errors:

It has never failed on gcc before, but it didn't try building flex this time either.

I have tried building mxe-octave in Ubuntu (in Virtual Box) with the
intent of eventually cross compiling for Windows, but I'd be happy if
I could get a linux version. I want many of the bug fixes and
enhancements in the development version. I have used instructions
from http://wiki.octave.org/Windows_Installer,
http://wiki.octave.org/MXE, and
http://wiki.octave.org/Octave_for_Debian_systems. Compilation fails
while building flex. How can I fix the problem with building flex, or
compile octave using the installed version of flex? I've tried a few
things to avoid building flex, but I'm not sure exactly how to do
that, e.g. ./configure --without-flex or make PKG_EXCLUDE='flex', and
other variations. I can't find it now, but I've seen a partial answer
on the help email list to a similar problem of setting some make
option or looking at one of the .mk files for guidance suggesting that 
building make shouldn't have to be done. How can I do that?
What options do you pass to configure when building, and what error occurs? 

For creating a 64 bit windows installer I use the following configure
options:

./configure --enable-devel-tools --enable-binary-packages
--enable-octave=default --enable-qt5 --enable-64 --enable-windows-64

For creating a linux native, I use:

../configure --enable-devel-tools --enable-binary-packages
--enable-octave=default --disable-system-opengl --enable-native-build
--enable-lib64-directory --enable-pic-flag --disable-system-x11-libs
--disable-system-fontconfig --disable-system-gcc --enable-qt5
gnu-linux




For each was it a clean build ? ie:
# make clean
# ./configure --enable-devel-tools --enable-binary-packages --enable-octave=default --enable-qt5 --enable-64 --enable-windows-64 
# make

What version of Ubuntu ?




That looks more like a running out of memory during compile.

Increase the memory used by the VM, and perhaps use a smaller job count
