Follow-up Comment #35, bug #48519 (project octave):

I don't see immediately why it fails in these lines.

I tried to replicate (with Pantxo's second patch on top of af7faef288ad). But
compiling after:

make maintainer-clean
cd .build
../configure CPPFLAGS=-I/usr/include/hdf5/serial
LDFLAGS="-L/usr/lib/$(dpkg-architecture -qDEB_HOST_MULTIARCH)/hdf5/serial"
FFLAGS=-g CFLAGS=-g CXXFLAGS=-g --enable-address-sanitizer-flags
--disable-java
make -j3


Fails with:

  GEN      doc/interpreter/voronoi.txt
  GEN      doc/interpreter/triplot.txt
  GEN      doc/interpreter/griddata.txt

Am I doing something wrong?
Is it necessary to compile with address-sanitizer-flags to reproduce?

@Hartmut: Does it always fail for you in octave::opengl_renderer::set_normal
with the same (or a similar) backtrace like in your comment #33?
(For a backtrace just type "bt" at the gdb prompt.)
