(In reply to Gregor Münch from comment #5) > Ive tested this now, and again its a compiler flags issue. > Arch standard clfags are: > CFLAGS="-march=native -O2 -pipe -fstack-protector-strong" > for clarity, default on archlinux is NOT -march=native . The current pacman version is 5.0.2-2 and it has these defaults : # ARCHITECTURE, COMPILE FLAGS ######################################################################### # CARCH="x86_64" CHOST="x86_64-pc-linux-gnu" #-- Compiler and Linker Flags # -march (or -mcpu) builds exclusively for an architecture # -mtune optimizes for an architecture, but builds for whole processor family CPPFLAGS="-D_FORTIFY_SOURCE=2" CFLAGS="-march=x86-64 -mtune=generic -O2 -pipe -fstack-protector-strong -fno-plt" CXXFLAGS="-march=x86-64 -mtune=generic -O2 -pipe -fstack-protector-strong -fno-plt" LDFLAGS="-Wl,-O1,--sort-common,--as-needed,-z,relro,-z,now" #-- Make Flags: change this for DistCC/SMP systems #MAKEFLAGS="-j2" #-- Debugging flags DEBUG_CFLAGS="-g -fvar-tracking-assignments" DEBUG_CXXFLAGS="-g -fvar-tracking-assignments" --------------------------------------------------
