You're certainly not the only one:

* Seastar is a C++ userspace TCP/IP stack, ScyllaDB is based on it.
* Click modular router can use DPDK from C++ [1].
* DPDK-based product out company works on is in C++.

Can't speak for Seastar and Click, but we never hit this particular issue.
What is the minimal complete example to reproduce?
