I've got following installation:
* ping 32 bit version
* Linux 4.4.0 x86_64 (yes, somewhat ancient)
* iproute2  4.9.0 or 4.20.0 or 5.10.0

With one ping command active, there are two raw sockets on my system:
one for IPv4 and one for IPv6 (just one of those is used).

My problem is that

ss -awp

shows 
* two raw sockets (4.9.0)
* any raw socket = bug (4.20.0)
* any raw socket = bug (5.10.0)

Could you clarify how the bug manifests itself? Does ss crash?

I take it kernel version is constant and iproute2 version changes,
correct? Can you download the source and do a git bisect?

So is this a bug or is this wont-fix (then, if it is related to
kernel version, package maintainers may be interested)?
