OpenBLAS: symmetric matrix inversion giving incorrect results

For the latest version of OpenBlas, calling potrf then potri is giving incorrect results for the particular example below.

When I run it with 3.6, I get

> g++ cholesky_test.cc /3rd_party/OpenBLAS-0.3.6/libopenblas.a -lpthread
> ./a.out
-0.0915173

If I run with the version installed by my package manager, I get the correct result

> g++ cholesky_test.cc -lopenblas
>  ./a.out
2.21785e-06
> dpkg -s libopenblas-dev
