[Octave-bug-tracker] [bug #46330] segfault with matrices containing Inf & NaN

[John W. Eaton]

Follow-up Comment #33, bug #46330 (project octave):

For the examples


[Inf 1; 1 1] \ [4; 3] % Matlab [0; 3]
[nan 1; 1 1] \ [4; 3] % Matlab [nan; nan]


I'm still seeing this:


octave:1> [Inf 1; 1 1] \ [4;3]
warning: matrix singular to machine precision
warning: matrix singular to machine precision
 ** On entry to DLASCL parameter number  4 had an illegal value
error: exception encountered in Fortran subroutine dgelsd_
octave:1> [nan 1; 1 1] \ [4;3]
warning: matrix singular to machine precision, rcond = nan
 ** On entry to DLASCL parameter number  4 had an illegal value
error: exception encountered in Fortran subroutine dgelsd_


In comment #29 Mike said that the patch should avoid calls to XERBLA, but that
doesn't seem to be the case.

I'm using HG ID  8971508e21c8.
