julia version 1.4.1-2 the problem persists...

With julia-1.4.1-2, I don't have the file `/usr/lib/julia/libLLVM-8.so` only `/usr/lib/julia/libLLVM-8jl.so` and `/usr/lib/julia/libLLVM.so`. Something is maybe wrong with your install.

Today, I tried it again. No julia packages were installed on my system and archlinux was fully updated. Clean install julia "pacman -S julia", one dependency has been installed too 'openlibm-0.7.0-1".. Then opening terminal and call julia:

:~$ julia

My second notebook computer with Intel Sandybridge CPU has no problems at all with julia. I know my CPU is an older one but codepaths with newer instruction sets should be selected at runtime and not be mandatory for archlinux.

As a workaround, you can rebuild the package with MARCH=amdfam10

Sorry, but the x86-64 instruction set is not a problem, it is actually more restricted then the one of my cpu. I tried to rebuild the whole julia package with MARCH=amdfam10 and MARCH=x86-64. Got the same results shown below:

Breche ab...

Did you try with julia precompiled binaries from their website (https://julialang.org/downloads/)?
If it is not working with these binaries you should report to upstream, no?

@getzze it is already reported upstream, see the link I posted above.

I found that adding 'USE_BINARYBUILDER=0' to flags in PKGBUILD fixes both problems, building the package and the runtime crash.

Please test 1.5.0, which uses system LLVM

julia 1.5.0 works fine!
