[Octave-bug-tracker] [bug #42512] qr with permutation fails with --enable-64

[John W. Eaton]

Follow-up Comment #7, bug #42512 (project octave):

How did you build the dependencies for Octave?  Were you careful to follow the
directions here

http://www.gnu.org/software/octave/doc/interpreter/Compiling-Octave-with-64_002dbit-Indexing.html#Compiling-Octave-with-64_002dbit-Indexing

especially the part about enabling 64-bit integers for all Fortran
dependencies?

If you think you did build and link with the libraries correctly, are you sure
you are using them when you run Octave?  You may need to set LD_LIBRARY_PATH
in your environment so that Octave links with the libraries you built instead
of other 32-bit versions of those libraries that may be installed.

I'm unable to duplicate the problem with a 64-bit build when I'm using
properly built dependency libraries, but if I don't set LD_LIBRARY_PATH
appropriately, I get a segfault when trying your example.
