[Octave-bug-tracker] [bug #31861] crash with empty function line

[John W. Eaton]

Follow-up Comment #12, bug #31861 (project octave):

It is possible, but I would be surprised if this problem is related to the
--enable-64 configure option.  But in any case, I don't think you want to use
that unless you are also using custom-built numerical libraries.  Please read
the description of building with --enable-64 in the file INSTALL.OCTAVE for
more info.

As for the other configure options that you are using, where did you get the
idea that you should use -fPIC for CFLAGS and CXXFLAGS?  That disables
compiler optimization and the configure script (really libtool) is supposed to
determine whether options like -fPIC are needed.  Similarly, you should not
need to specify -lblas.  That is one of the libraries that should be checked
by default.  Adding -fdefault-integer-8 to the --with-blas option makes no
sense as far as I can tell.  Using "--with-cholmod=-lcholmod -lcamd -lccolamd
-lmetis" also does not make sense to me.

BTW, do you have more than 16GB of memory?  Do you regularly work with
integer arrays with more than 2e9 elements?  If not, then I don't think there
is any need to build with --enable-64.
