Thanks. This may be related to the OpenBLAS library, see for example upstream bug report https://savannah.gnu.org/bugs/?47400.
I am unable to reproduce with 4.2.1 on Ubuntu 17.10, but this may be affected by the specifics of your system or timing. Can you try again with OpenBLAS multi-threading disabled, with the following tests: 1. env OMP_NUM_THREADS=1 octave --no-gui 2. sudo update-alternatives --set libblas.so.3-x86_64-linux-gnu /usr/lib/x86_64-linux-gnu/blas/libblas.so.3 sudo update-alternatives --set liblapack.so.3-x86_64-linux-gnu /usr/lib/x86_64-linux-gnu/lapack/liblapack.so.3 octave --no-gui The names and paths of the blas and lapack alternatives may differ on your system. If both of these tests resolve the crash for you, then this looks like https://savannah.gnu.org/bugs/?47400. ** Bug watch added: GNU Savannah Bug Tracker #47400 http://savannah.gnu.org/bugs/?47400 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1695281 Title: GNU octave crashes reliably after a simple input sequence To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/octave/+bug/1695281/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
