I got in touch with MKL team and they confirmed that the iomp+gomp mixture is actually a very common error among users. They plan to change the loading mechanism of libmkl-rt for the 2020 production line, to avoid iomp+gomp clash (sounds like yet another magic). So let's keep this bug open for both MKL and Octave for a while, in case any other user came across similar errors. Maybe this bug will be fixed in the late 2019 (they released MKL 2019 in late 2018).
