Trying to update octave to 4.2 in rawhide, I'm running into a segfault in libgcc when throwing an exception: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78409 Is anyone else running into this? Running on Fedora rawhide with gcc-6.2.1-2.fc26 Core was generated by `/home/orion/fedora/octave/octave-4.2.0/src/.libs/lt-octave-gui --no-init-path -'.
