Without knowing anything about SU2, we can't really help debug the issue. The seg fault stack trace that you provided was quite deep; we don't really have the resources to go learn about how a complex application like SU2 is implemented -- sorry!
Can you or they provide a small, simple MPI application that replicates the issue? That would be something we could dig into and investigate. ________________________________ From: Aziz Ogutlu <aziz.ogu...@eduline.com.tr> Sent: Wednesday, August 9, 2023 10:31 AM To: Jeff Squyres (jsquyres) <jsquy...@cisco.com>; Open MPI Users <users@lists.open-mpi.org> Subject: Re: [OMPI users] Segmentation fault Hi Jeff, I'm using also SU2 lastest version, also open issue on github page. They says it could be about OpenMPI :) On 8/9/23 17:28, Jeff Squyres (jsquyres) wrote: Ok, thanks for upgrading. Are you also using the latest version of SU2? Without knowing what that application is doing, it's a little hard to debug the issue from our side. At first glance, it looks like it is crashing when it has completed writing a file and is attempting to close it. But the pointer that Open MPI got to close the file looks like it is bogus (i.e., 0x30 instead of a real pointer value). You might need to raise the issue with the SU2 community and ask if there are any known issues with the application, or your particular use case of that application. ________________________________ From: Aziz Ogutlu <aziz.ogu...@eduline.com.tr><mailto:aziz.ogu...@eduline.com.tr> Sent: Wednesday, August 9, 2023 10:08 AM To: Jeff Squyres (jsquyres) <jsquy...@cisco.com><mailto:jsquy...@cisco.com>; Open MPI Users <users@lists.open-mpi.org><mailto:users@lists.open-mpi.org> Subject: Re: [OMPI users] Segmentation fault Hi Jeff, I also tried with OpenMPI 4.1.5, I got same error.

Many bug fixes have been released since that version. Can you upgrade to the latest version of Open MPI (v4.1.5)? ________________________________ From: users <users-boun...@lists.open-mpi.org><mailto:users-boun...@lists.open-mpi.org> on behalf of Aziz Ogutlu via users <users@lists.open-mpi.org><mailto:users@lists.open-mpi.org> Sent: Wednesday, August 9, 2023 3:26 AM To: Open MPI Users <users@lists.open-mpi.org><mailto:users@lists.open-mpi.org> Cc: Aziz Ogutlu <aziz.ogu...@eduline.com.tr><mailto:aziz.ogu...@eduline.com.tr> Subject: [OMPI users] Segmentation fault Hi there all, We're using SU2 with OpenMPI 4.0.3, gcc 8.5.0 on Redhat 7.9.
