Error while generating documentation

Hi, I am testing building with this repo.

I get the following error while generating the docs

  GEN      doc/interpreter/splinefit6.eps
error: index 0: subscripts must be either integers 1 to (2^63)-1 or logicals
error: called from
    __splinefit__>solvecon at line 557 column 17
    __splinefit__ at line 149 column 12
    splinefit at line 156 column 6
    splineimages at line 120 column 9
  GEN      doc/interpreter/voronoi.pdf

the octave executable is generated but then when I test it I get

octave-gui:1> clear all;
octave-gui:2> N = 2^31;
octave-gui:3> ## The following line requires about 8 GB of RAM!
octave-gui:3> a = b = ones (N, 1, "single");
octave-gui:4> c = a' * b
SSYRK : parameter number -8358843910998458364 is invalid
error: Fortran procedure terminated by call to XERBLA

Are the two errors related?
