Details:

So I just compiled 3.8.2 using gcc4.9 on my new 64 bit computer (debian
testing) with the following options:

CFLAGS -O3 -mfpmath=sse -fomit-frame-pointer -march=native -s

configure --enable-64 --enable-jit
--with-blas=/opt/OpenBLAS/lib/libopenblas_nehalemp-r0.2.10.so
LLVM_CONFIG=/usr/bin/llvm-config-3.3

make -j2


Unfortunately I'm not having a fun time. One of my codes gives this error:

octave:1> fval=[3.4422e+06   3.4255e+07   3.0596e+06];
octave:2> range=[0.00000   1.00000   0.33333];
octave:3> polyfit(range,fval,2)
error: qr: subscript indices must be either positive integers less than 2^63
or logicals
error: called from:
error:   /usr/local/share/octave/3.8.2/m/polynomial/polyfit.m at line 114,
column 10
octave:3> 


I am thinking this is something related to 64 bit indexing. I found this
page:

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

I was kind of hoping this is outdated and things are auto-magic these days,
now that 64 bit is more popular... Is it so?
