Details:

Example:

>> symbfact([1])


Expected result:

ans = 1


Observed result: Varies on each call. Sometimes the expected result. Sometimes
a wrong result. Sometimes a warning and error like

>> symbfact([1])
warning: warning -3, at line 89 in file ../Core/cholmod_sparse.c: problem too
large
warning: warning -4, at line 219 in file ../Cholesky/cholmod_rowcolcounts.c:
argument missing
error: symbfact: matrix corrupted

And other times Octave just crashes.

This happens for me on Octave versions 5.2.0, 6.1.0 and 6.2.0, but only on
Windows. On Linux everything works as expected. Also on both Windows and Linux
everything works as expected when using a sparse matrix, e.g.

symbfact(sparse([1]))
