| | Yes.
| | 
| | LAPACK is build with:
| | 
| | OPTS     = -O2 -march=native -fdefault-integer-8 -fPIC
| | 
| | and Goto BLAS with:
| | 
| | BINARY=64
| | 
| | and
| | 
| | INTERFACE64 = 1
| 
| To debug the problem, you can start by going to the test directory of
| your build tree and running
| 
|   ../run-octave -g --norc --silent --no-history $srcdir/fntests.m $srcdir
| 
| where $srcdir should be replaced by the name of the directory where
| the sources for the test directory are.  Then type
| 
|   b main
|   r
|   b error
|   b xstopx
|   c
| 
| at the (gdb) prompt.  Then when you get to the error about the bad
| parameter passed to DGEMV, you should end up back at the debug prompt,
| inside the xstopx_ or error function.  Then get a backtrace by typing
| 
|   where
| 
| at the gdb prompt and let us know where the call to DGEMV is (file and
| line number).  That might give a clue.

Also, are you sure you are linking to the correct libraries at run
time?  What does

  ./libtool --mode=execute ldd src/octave

tell you?

I'm able to build with --enable-64 and link with the reference
BLAS+LAPACK, both compiled with gfortran -fdefault-integer-8 and all
tests pass except one, the same one from data.cc that fails when I
build a 32-bit binary without optimization.
