Error with 'int8'

[chuksyee]

I had compiled GraphBLAS-9.4.2 from source code with gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0.
When running the test suite "gbtest", the test fails at gbtest1 when it uses the type 'int8'. I tried running the gbtest1 manually by typing out each command at octave command-line as shown below. When I use type 'double' or 'uint8', it works fine. Would you know the reason for this error? Thanks for your help.

octave:4> rng ('default') ;
octave:5> X = 100 * sprand (3, 4, 0.4)
X =
Compressed Column Sparse (rows = 3, cols = 4, nnz = 5 [42%])

  (3, 2) -> 47.660
  (1, 3) -> 30.331
  (3, 3) -> 58.338
  (1, 4) -> 78.380
  (2, 4) -> 40.493

octave:6> m = 2 ;
octave:7> n = 3 ;
octave:8> A=GrB(X,'int8')
error:

I forgot to mention I was using octave-8.3.0.
