While working on some functions based on LowRankApprox.jl I got an EXCEPTION_ACCESS_VIOLATION error in a MKL dll.
Sadly, I was not able to make a MWE from my original code that shows the issue.
My script uses a pqr decomposition from LowRankApprox. When I switch back to a standard qr the script runs fine.
Surprisingly, the computation seems to fail once I actually try to access the factors of the QR decomposition with e.g. F.Q if the computation was done with F = pqrfact(A)
Frankly, I can’t figure how to provide more information about this issue. I’m open to suggestions 
Additional information.
This problem does not show up with julia 1.6.0 with OpenBLAS, so this seems definitely related to MKL
