Secondary lldb process output

Linux:
AlmaLinux 9.3

Kernel:
5.14.0-362.8.1.el9_3.x86_64

Software version:
rdma-core-48.0-1.el9.x86_64
dpdk-v22.11(tested on git branch v23.11-rc4 as well)

Hardware:
Mellanox Technologies MT27800 Family [ConnectX-5]

Running two testpmd processes at the same time causes the secondary process=
 to
crash with a segmentation fault from the libmlx5.so library. Two ports on a
Mellanox MT27800 card are configured to be used by both testpmd apps.
The two separate instances are launched:
1. dpdk-testpmd --proc-type=3Dprimary
2. dpdk-testpmd --proc-type=3Dsecondary

I am not sure if this is a rdma-core issue which contains the libmlx5.so
library where segmentation fault is thrown from. The primary dpdk process r=
uns
without any issues and there are no segfaults. The rte_eth_stats_get functi=
on
only throws an error on the secondary process, not on the primary process.=
=20
Attached is the lldb output when running a debug build secondary process wi=
th
lldb.

Running dmesg also shows that there is a segfault:
