=sys-apps/memtest86+-5.01-r4 crashes after few seconds if built with sys-devel/gcc-8.2.0-r6 on my Phenom II X4 965 BE (amd64). I tried with CFLAGS="-march=native -pipe -O2 -mfpmath=sse" In the same system and with the same or more aggressive cflags it works when built with sys-devel/gcc-7.3.0-r6
Please post your `emerge --info' output in a comment.

I happened to find that the coreboot project maintains a fork at https://review.coreboot.org/cgit/memtest86plus.git/, maybe that's worth looking at?
I have very similar issue with sys-apps/memtest86+-5.01-r4 built with gcc-8.3.0-r1 on my AMD Phenom II X6 1090T (amd64). After few seconds of testing my PC reboots. But when built with gcc-7.3.0-r3 it work as it should. No errors found with memory testing, so hardware is ok.

Just hit the same, memtest hangs after a short while. Compiled with gcc version 9.2.0 (Gentoo 9.2.0-r1 p2). CPU is Celeron(R) CPU G3930. No problems with official binary from www.memtest.org, so this is not a hardware error.
FWIW I too get a reboot shortly after it starts. I'm compiling with x86_64-pc-linux-gnu-8.3.0, and running on a legacy BIOS booting AMD64 system.
Seems like I found the cause. Thanks for coreboot repo link! https://review.coreboot.org/c/memtest86plus/+/36715
Created attachment 626432 [details, diff] Patch for Makefile (In reply to Igor V. Kovalenko from comment #8) > Seems like I found the cause. Thanks for coreboot repo link! > > https://review.coreboot.org/c/memtest86plus/+/36715 I can confirm this bug as well with x86_64-pc-linux-gnu-9.2.0. In my case the computer only locks up shortly after the tests start. I have created the attached patch which resolves the problem in my case. It would be great so see it added to the main tree.
I have two machines that appear to run memtest86+ incorrectly when built from Gentoo. My third gen i5 would reboot about 2 seconds into the first test. My second gen i7 would report millions of errors implying the RAM was *really* bad. I first got tipped off by a potential compile error when I have a memtest86+-5 binary that appears to work properly on both of these machines. Getting new RAM I needed to test whether the RAM is good. Memtest86+'s behavior was so bad that it seems like Linux shouldn't run, but both machines booted and ran seemingly without hitches despite the memory failures. After applying the patch that Igor mentioned in comment 8, both the rebooting and the RAM errors went away. I find it kind of confusing that it seems some people have it working just fine without the patch which bothers, and having it needed for two machines here seems to indicate that this is a widespread issue.
