I got this email from Noda Akira, who submitted the original PR. (I added his email address to the receipients.) I just tried it, and it didn't fix it. But now I am trying it using clang instead of gcc to build it. Hi I think some patch file is missed. patch-libinterp-octave-value-ov-classdef.cc patch-libinterp-octave-value-ov-classdef.h # #Please see this attachment of the PR site #https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D201737 # Without this, you will always have core dump (with gcc) I think clang can not build this source with out patch.
