Details:

I am running Fedora 23 with the packaged gcc-5.1.1-4 and octave-4.0.0. I have
a project with a test suite of bash shell scripts, most of which run the
octave interpreter and check the results. I have been getting seg-faults from
octave. Usually, I would assume that this means that I have a hardware
problem. I decided to check the octave interpreter with Address-Sanitizer. I
built octave from the hg sources, as recommended in HACKING, with this shell
script:

#!/bin/sh
uname -ro
hg clone http://hg.savannah.gnu.org/hgweb/octave/
cd octave
./bootstrap
mkdir .build
cd .build
CXXFLAGS="-fsanitize=address -fno-omit-frame-pointer"
export CXXFLAGS
CFLAGS="-fsanitize=address -fno-omit-frame-pointer"
export CFLAGS
LDFLAGS="-fsanitize=address"
export LDFLAGS
../configure --without-fltk --disable-gui --disable-java \
--enable-bounds-check --disable-docs
make LDFLAGS="-fsanitize=address" -j 6
make check

The "make check" ends when address-sanitizer finds a problem in
scripts/sparse/ichol.m. The address-sanitizer stack trace is attached.
