Does this box pass overnight memtest86? andrew@alshain.org.uk 2004-06-17 23:43:13 0000 I thought memtest86 was only for the x86. Certainly it causes my machine to reboot instantly. Everything else works fine. mr_bones_@gentoo.org 2004-06-18 00:06:08 0000 memtest86-3.0-r1.ebuild claims to be stable on amd64. Please try it out. andrew@alshain.org.uk 2004-06-18 08:11:52 0000 From the memtest86 Changelog: 18 Jun 2004; Jeremy Huddleston <eradicator@gentoo.org> memtest86-3.0-r1.ebuild: This contains 32bit x86 assembly and won't work on amd64. I seriously doubt it's a hardware problem as 0.82.1 compiles and I have no problem compiling any other software on my machine, and it's extremely stable. andrew@alshain.org.uk 2004-06-18 14:22:27 0000 Okay, I think I've solved the problem. Looking at the top level Makefile shows a line: CFLAGS=-O2 -march=athlon64 -mtune=athlon64 -pipe -maccumulate-outgoing-args -fomit-frame-pointer -fweb -Wno-unused -fomit-frame-pointer -fstrict-aliasing -fstrength-reduce -ffast-math -falign-functions=2 -falign-jumps=2 -falign-loops=2 -O -Wall -Wno-unused If I remove -ffast-math it appears to compile correctly. I've noticed that another program that uses the -ffast-math option, xephem-3.6, also segfaults. This also compiles correctly when I remove -ffast-math, so maybe it's a compiler bug. I'm using gcc-3.4.0-r6. mr_bones_@gentoo.org 2004-06-18 14:44:39 0000 Nice work. Thanks for tracking it down. I've taken out the -fast-math stuff for amd64 in the ebuild. No rev bump since it's such a beast to compile (at least for everyone except amd64).
