Comment 4 Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2016-12-22 20:16:43 UTC
Looks like segfault in GCC.
Comment 5 Mark Nowiasz 2016-12-30 20:19:59 UTC
Got a different segfault:

/var/tmp/portage/sys-devel/llvm-3.9.1/work/llvm-3.9.1.src/lib/Target/X86/X86MCInstLower.cpp:1686:1: internal compiler error: Segmentation fault

(gcc 5.4.0)
Comment 6 Mark Nowiasz 2016-12-31 12:01:12 UTC
Cancel my last comment: I found one of my 4 memory modules to be faulty, thus causing the segmentation fault.
