You're right, sorry for the noise.
Point is, I didn't hit 57727 when searching the bug tracker for "Octave Qhull.

You filed a similar issue a few months back: bug #57727

Closing as duplicate.

Since several months I get the following Qhull messages during __run_test_suite__.m on Windows:

:

I know about bug #57703 but that one had been closed as fixed. In addition all tests do pass here. In bug #57703 I read nothing about these remaining messages.
So seemingly these are just cosmetic issues but unnecessarily verbose IMO. BIST test adaption required? Is there a way to silence Qhull?

My mxe-octave build tree is up-to-date. On Mageia 7 Qhull is at 2015.2
