[Bug 2043823] [NEW] valgrind shared memory programs

Fri Nov 17 17:10:25 UTC 2023

Public bug reported:

Unexpected error occurred attempting to attach to shared memory.

This worked fine in ubuntu 20 with our APP. But is failing on ubuntu 22.
I tried the latest valgrind from the internet also, same thing.
