After cleaning up my build, I do end up with the same crash:

............................................................................................................................ESSSSSSSSSSSB->ncol
= 1  Bstore->lda = 5  A->nrow = 5
B->Stype = 5  B->Dtype = 0  B->Mtype = 0
** On entry to sgssv, parameter number 7 has an illegal value.
Segmentation Fault (core dumped)

With verbose=10:

Solve with UMFPACK: double precision ... SKIP: UMFPACK appears not to
be compiled
Solve: single precision ... SKIP: UMFPACK appears not to be compiled
test_twodiags (test_linsolve.TestLinsolve) ... B->ncol = 1
Bstore->lda = 5  A->nrow = 5
B->Stype = 5  B->Dtype = 0  B->Mtype = 0
** On entry to sgssv, parameter number 7 has an illegal value.
Segmentation Fault (core dumped)
