I am unable to reproduce. Are you using an external HWLOC installation perchance? Can you share a backtrace of the segv (compiling with -g).

Thanks. Can you share your config.log? I am unable to reproduce, neither on a RHEL box nor ubuntu v18.04.

@mwheinz can this issue be closed?

No worries - thanks.

master: https://github.com/open-mpi/ompi/pull/9302 v5.0.x: https://github.com/open-mpi/ompi/pull/9313 I thought we decided to leave these changes in master/v5.0.x as-is, and make a different change for v4.0.x/v4.1.x. Is that accurate @jsquyres @gpaulsen ?

These are coming from ROMIO, and will need to be addressed upstream, and pulled in via a romio update.
