Is SSE2 CPU extension really needed for SteamCMD?

I installed an old computer as LAN server for our small private LAN party and wanted to set up an CS:GO server with our own stats etc.

The computer has an Athlon XP 1900+ CPU in it which should be supported as written here: Steam for Linux > Limited Beta > Getting Started

Now is the question whether this is a bug at the moment or not. Will it be fixed or will the system requirements are fixed?

The steamCMD crashed with "illegal instruction" and after searching the web I found some hints that this could be an SSE2 error. This makes sense to me (software developer for embedded systems).

Here a list of SSE support of CPUs until 2006: ( [])

Would be nice to get information about this (so I can wait or put the server to a virtual machine or other hardware).

This is certainly frustrating. I have a Poweredge with dual PIIIs at 1.2 ghz each. Should be plenty, but it doesn't have SSE2.From what I understand, this isn't necessary in the Windows steam CMD.

Yes, AMD Athlon XP 1900+ (K7) doesn't support SSE2 instructions. Steam needs at least Opreton (K8) or Pentium-4 as said in that link.
No, it's not a bug, SSE2 support is really required to run Steam (at least, on Linux). It will probably hardly be fixed any time soon, if ever. Valve doesn't care about "old hardware", over 99% users have SSE2 anyway.
There was a similar thread here not long ago.
"Illegal instruction" means that the instruction is not supported in CPU instruction set (or the program reads an instruction from the wrong place, or reads it wrong). Shortly, yes, it's because 1900+ has no SSE2.
PS. SSE != SSE2.

I'm having the same issue here. I would love to see this bug fixed.

It's not a bug, it's a design choice.
Steam decided for whatever reason only support CPUs with that feature and not older ones.
Do you cry over Steam not supporting PowerPC Macs either?
