[Octave-bug-tracker] [bug #47400] panic on Ctrl+c with multithreaded ATLAS or OpenBLAS

[Lachlan Andrew]

Follow-up Comment #12, bug #47400 (project octave):

Thanks for testing, Ben.

The part on toplev.cc has moved to interpreter.cc.  (See the attached patch.) 
However, it doesn't affect the part that is supposed to stop the ^C errors.

I seem to recall that MacOS had issues other than just the BLAS.  Can you
avoid the ^C error by running the BLAS single-threaded as Rik suggested in
comment #7?

Also, this patch relies on the undocumented effect that Rik noticed: On Linux,
calling popen seems to shut down unnecessary BLAS threads.  I wasn't expecting
this patch to work on OSX or Windows.  This bug is currently marked as a Linux
bug.
