[Octave-bug-tracker] [bug #44285] "test eigs" never returns when built with SuiteSparse 4.4.3

[Mike Miller]

Follow-up Comment #2, bug #44285 (project octave):

All tests in the "Complex hermitian tests" block that are marked with
HAVE_UMFPACK hang. If I comment them all out, `test eigs` finishes
successfully. All of them are blocked in the function cholmod_divcomplex,
which never returns (Ctrl-C followed by the `finish` command to gdb shows that
the function never returns).

Example top of the stack:


#0  cholmod_divcomplex (ar=-0, ai=-1, br=4, bi=0, cr=0xdde838, ci=0xdde840)
    at ../Core/cholmod_complex.c:60
#1  0x00007ffff1460a8b in umfzi_scale (n=<optimized out>, pivot=...,
X=<optimized out>)
    at ../Source/umf_scale.c:78

    User_Info=0xe8a910) at ../Source/umfpack_numeric.c:289
#5  0x00007ffff5feb194 in SparseComplexLU::SparseComplexLU
(this=0x7fffffff6ae0, a=...,

It could be a bug in the library, or it could be something we need to call or
configure differently before using the same functions that used to work.
