Hello,
I upgraded one of the systems to v5.0.1 and have compiled everything
exactly as dozens of previous times with v4. I wasn't expecting any issue
(and the compilations didn't report anything out of ordinary) but running
several apps has resulted in error messages such as:

OS is Ubuntu 22.04, OpenMPI was built with GCC13.2, and before building
OpenMPI, I had previously built the hwloc (2.10.0) library at
/usr/lib/x86_64-linux-gnu. Maybe I'm missing something pretty basic, but
the problem seems to be related to memory allocation.
Thanks.
