Looking at the build logs for Debian's 2.34-8 [1], 2.35-4 [2] and 2.36-4 [3], it's obvious there is something wrong given the many "Segmentation Fault" errors. I had hoped I could fix this issue by passing "--disable-default-pie" like we already did on sparc64, but it seems it's not the same bug [4]. At least, this particular workaround does not help.Interestingly the vast number of the failing tests pass if one builds with a compiler that raises the baseline to EV67. This has been proposed a number of times in the past for the Debian distribution. I think it is time we did it. One of our last EV56 users has recently bowed out due to hardware failure and I am only running EV67 hardware.
I still have the following pre EV67 machines available and in working order: * AXPpci 33 (LCA4) * AlphaStation 200 (EV4) / 255 (EV45) / 500 (EV56) * PWS 500au (EV56) * AlphaServer 800 (EV56) ...and can provide testing on them. All of them eventually ran Debian GNU/Linux Sid with up to Linux 5.x.x IIRC and I will also try them with 6.0.x. And I believe the majority of still exsiting, still working Alpha systems are pre EV67 systems. Given the fact that EV6[...] and EV7[...] based systems are nowadays very expensive for hobby use (I don't want to say unobtainium), I expect that dropping support for pre EV67 will kill off most of the user base for Debian on Alpha (and also Gentoo I assume). Phrasing it differently: Who needs a port that only runs on the buildds and a handful of (hobbyist) machines around the world (like ppc64le ;-))? My two cents. All the best, Frank
