Follow-up Comment #6, bug #53140 (project octave):
If my previous consideration is valid, this is the difference between
SparseMatrix::fsolve in stable and default branch
2c2
< SparseMatrix::fsolve (MatrixType& mattype, const SparseMatrix& b,
---
> SparseMatrix::fsolve (MatrixType &mattype, const SparseMatrix& b,
39c39
< SUITESPARSE_ASSIGN_FPTR (printf_func, cm->print_function,
nullptr);
---
> SUITESPARSE_ASSIGN_FPTR (printf_func, cm->print_function, 0);

< A->nz = nullptr;
---
> A->nz = 0;

< if (A->x == nullptr)

< B->nz = nullptr;

> B->nz = 0;

< if (B->x == nullptr)

> if (B->x == 0)
