Common Crash and Waypoint Flaw Options

[RoboCop]

Well just to avoid confusion I've compiled two versions of RCBot1: first is the main version that supports DMC, HLDM, TFC, RC etc, while the second version is only supported for Sven Co-op v5.

As some of you know already that the src code I've salvaged that was built for Sven 4.5 many years ago, and I've managed to add the important new SC 5 weapon entities and all of that - despite that they cannot shoot nor attack.

I've been making about a dozen waypoints for DMC and I've noticed some crashes linked to the Segmentation Fault from 'WaypointFindPath(path**, int*, int, int)'. This crash also appears to occur for the RCBot Sven side as well. I don't know if my waypoints needs compatibility fixes as well for this latest version of the RCBot build, but here is the crash GDB backtraces I've got:-

Well it appears Valve only allows support for 32-bit libs and binaries for HLDS and SRCDS, so far. They did introduce AMD64 support since 2004 until 2007 for Linux builds. But it seems recommended to have the builds only compatible for the i386 libs as they only work in 32-bit mode but will be compatible for 64-bit servers, despite the software not boosted or optimised natively for AMD64 or x86-64.

Jussi had made note on his site on how Valve dropped support on hlds_amd64, 10 years ago.

http://jukivili.kapsi.fi/web/amd64.binaries.html

And Valve made a tutorial for using SteamCMD to install the essential 32-bit libs for 64-bit Linux servers:-

But Windows don't need those 32-bit lib dlls as they will work fine.

And those optimisations for SSE2 and other opt flags should be more benefical for newer CPUs as well having tuned for Pentium 4 or over.
