Summary: Solving systems using complex NaN causes crash
Project: GNU Octave
Submitted by: lachlan
Submitted on: Sun 19 Jul 2015 10:31:18 AM GMT
Category: Octave Function
Severity: 3 - Normal
Priority: 5 - Normal
Item Group: Crash
Status: None

Open/Closed: Open
Discussion Lock: Any
Release: 4.0.0
Operating System: GNU/Linux
_______________________________________________________
Details:
The following code causes Octave 4.0.0 to crash:
coeffs = [
NaN - NaN*i NaN - NaN*i NaN - NaN*i NaN - NaN*i
NaN - NaN*i NaN - NaN*i NaN - NaN*i NaN - NaN*i
NaN + NaN*i 0 + 0i 0 + 0i 0 + 0i
0 + 0i NaN + NaN*i 0 + 0i 0 + 0i
];
rhs = [ NaN - NaN*i
NaN - NaN*i
NaN - NaN*i
NaN - NaN*i];
coeffs \ rhs
The diagnostics are:
octave: no graphical display found
octave: disabling GUI features
warning: matrix singular to machine precision
warning: called from
crash_small.m at line 15 column 8

I'm not sure if the issue is related to the following error. The following
code
coeffs = [
NaN - NaN*i NaN - NaN*i NaN - NaN*i
NaN + NaN*i 0 + 0i 0 + 0i
0 + 0i NaN + NaN*i 0 + 0i
];
rhs = [ NaN - NaN*i
NaN - NaN*i
NaN - NaN*i];
coeffs \ rhs
gives the error
warning: matrix singular to machine precision
** On entry to DLASCL parameter number 4 had an illegal value
error: exception encountered in Fortran subroutine zgelsd_
