[Octave-bug-tracker] [bug #61246] matrix inversions give wrong results (inv, lu, mldivide)

[John W. Eaton]

Follow-up Comment #20, bug #61246 (project octave):

I don't really understand the openblas build system but even though we set
TARGET=PRESCOTT I see the following in the log file:


sed -n 's/.*\(-DTS=[^ ]*\) .*/\1/p' openblas  | sort | uniq -c | sort -n
      3 -DTS=
    471 -DTS=_BARCELONA
    471 -DTS=_BOBCAT
    471 -DTS=_CORE2
    471 -DTS=_DUNNINGTON
    471 -DTS=_NANO
    471 -DTS=_OPTERON
    471 -DTS=_OPTERON_SSE3
    471 -DTS=_PENRYN
    471 -DTS=_PRESCOTT
    473 -DTS=_BULLDOZER
    473 -DTS=_EXCAVATOR
    473 -DTS=_PILEDRIVER
    473 -DTS=_STEAMROLLER
    475 -DTS=_ATOM
    475 -DTS=_COOPERLAKE
    475 -DTS=_HASWELL
    475 -DTS=_NEHALEM
    475 -DTS=_SANDYBRIDGE
    475 -DTS=_SKYLAKEX
    475 -DTS=_ZEN


so it looks like the sources are built for a variety of CPUs.

If the problem is solved by setting max number of threads, then I believe we
already made that change in the Windows startup script, correct?

I can still make a test release if you think that's the best option.
