      What were you trying to do that didn't work?

      --> Recently updated from 8 → 9. In the process, Lapack and related libs (which I use a fair bit) were updated from the el8 versions to el9, and (ii) I'm 95% sure there is a bug in the el9 packaging of the libs (code that compiles and runs perfectly on other el8 boxes now throws major segmentation faults on the el9 box when I try to run the executable).

      --> To rule out something related to the inplace upgrade, I also spun up el9 in a VM, and get the same segmentation faults there. Hence, being somewhat confident that the problem lies with the el9 versions of lapack .so files and related.

      --> Finally, and perhaps most importantly, if I download latest lapack source and compile libs manually, and link them, works fine. So - seems definitely connected to the libs installed with el9.

      What is the impact of this issue to you?

      Renders all my code that links lapack/blas to seg fault. 

      Please provide the package NVR for which the bug is seen:

      lapack-3.9.0-10.el9.x86_64

      How reproducible is this bug?:

      Most of my code (FORTRAN) that links lapack involves inversion of fairly large matrices. So, for all of said code, seg faults. If I compile the exact same code on el8 boxes, runs fine. 

      Steps to reproduce

      1.  
      2.

      Expected results

      No seg faults. 

       

      Actual results

      Seg faults.
