SIGBUS failure for misc/tst-bz21269 on i386

[Florian Weimer]

Has anyone else seen this failure?

I saw it with this kernel:

Linux buildvm-09.phx2.fedoraproject.org 4.15.3-300.fc27.x86_64 #1 SMP 
Tue Feb 13 17:02:01 UTC 2018 i686 i686 i386 GNU/Linux

The CPU has AVX2, but not AVX-512.  I couldn't reproduce it on another 
AVX2 machine.  The failure happened in the Fedora build environment, so 
I don't have a coredump.

Thanks,
Florian
