I am encountering a runtime error when starting VPP 19.04-rc0 (top-of-tree)
after updating to the latest version this morning.

I am running on RHEL 7.6 with its version of rdma-core:
# uname -a
Linux cl41.dpdk.nfv 3.10.0-957.el7.x86_64 #1 SMP Thu Oct 4 20:48:51 UTC 2018
x86_64 x86_64 x86_64 GNU/Linux
# rpm -qa | grep rdma-core
rdma-core-17.2-3.el7.x86_64
rdma-core-devel-17.2-3.el7.x86_64
#
I am using a ConnectX-5 adapter, so the MLX5 PMD is being included:
# make install-ext-deps DPDK_MLX5_PMD=y DPDK_CCP_PMD=y
# make pkg-rpm vpp_uses_dpdk_mlx5_pmd=yes
I have found that if I remove the VPP external "rdma-core" build, then VPP will
start successfully.
The following changes are used to avoid the issue:

is used:
