Subject Re: Make scalapkg fails if USE_BLAS is set to openblas/mkl/apple
Date Wed, 06 Jun 2018 07:28:19 GMT
Unfortunately, I think this is the same behaviour that we're observing on
Raspberry Pi's. Currently we are bisecting the release to find the breaking
commit to have an idea what exactly is broken.

What I can say for now that this failure is not deterministic (on RPi's)
and the library import to python passes in 1 of 4 times. The creation of
NDArray's in this case fails though in all cases with similar message that
the stack is corrupted.

Will update on findings.
