./configure
make
make check

many (but not all) checks in linalg fail.
first FAIL is:
        FAIL:   SV_decomp (3x3) A=[ 0, 0, 0; 0, 0, 1; 1, 1, 0] [852]
(several hundred later)
last FAIL is:
        FAIL: SV_decomp_mod (4x4) A=[ 1, 1, 1, 1; 1, 1, 1, 1; 0, 1, 0, 1; 0, 0, 
1, 1] [233613]

if the linalg tests are bypassed, all other checks pass.
