--- Comment #9 from robertgjenssen at gmail dot com --- The following apply to the log file attached in comment 8 (they got lost when I added the attachment): I triggered a similar problem by trying to build current octave sources with LTO and address-sanitizer: hg clone http://hg.savannah.gnu.org/hgweb/octave/ cd octave ./bootstrap mkdir build cd build export CFLAGS="-O3 -march=nehalem -flto -ffat-lto-objects" export CXXFLAGS="-O3 -march=nehalem -flto -ffat-lto-objects" ../configure --without-fltk --disable-java --enable-bounds-check \ --disable-docs --enable-address-sanitizer-flags \ --prefix=/usr/local/octave --program-prefix=asan- make -j 6 My uname and gcc version are: build# uname -a Linux morgawr 4.4.9-300.fc23.x86_64 #1 SMP Wed May 4 23:56:27 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux build# g++ -v Using built-in specs.
