[Octave-bug-tracker] [bug #39000] Can't override BLAS XERBLA handler on Windows

[Kai Torben Ohlhus]

Follow-up Comment #19, bug #39000 (project octave):

I have tested the patch of comment #18 on Linux without problems.  Calls like
in comment #17 result in a nice warning, like Matlab does.

Before:

>> [ Inf 1234 ] \ 5
 ** On entry to DLASCL parameter number  4 had an illegal value
error: exception encountered in Fortran subroutine dgelsd_


After:

>> [ Inf 1234 ] \ 5
warning: matrix singular to machine precision
ans =

   0
   0


But as said in comment #17, only one of many potential cases is fixed by this
patch.

Another nasty remark is the code formatting.  Please do not introduce multiple
empty lines and lines with only white space characters.  See
http://wiki.octave.org/C%2B%2B_style_guide.
