Hi, everyone,  
I am using Julia on a cluster. But I am having error from LLVM. Here is the steps I took:

```julia
$./julia

```

Here is the output for versioninfo():

```julia
julia> versioninfo()
Julia Version 0.6.2
Commit d386e40* (2017-12-13 18:08 UTC)
Platform Info:
  OS: Linux (x86_64-redhat-linux)
  CPU: Intel(R) Xeon(R) Gold 6148 CPU @ 2.40GHz

  LAPACK: libopenblas64_
  LIBM: libopenlibm
  LLVM: libLLVM-3.9.1 (ORCJIT, skylake-avx512)

```

I did `ll` on the file mentioned in the error:  
`$ ll ~/.julia/v0.6/LLVM/deps/build.jl`  
`-rw-r--r-- 1 xiaoqihu tug 3309 May 16 15:55 build.jl`

So I see that I don’t have write access for the file. Maybe that was the reason for the error. But when I try to change the access right using `chmod`, nothing changed:  
`$ chmod +w ~/.julia/v0.6/LLVM/deps/build.jl`  
`$ ll ~/.julia/v0.6/LLVM/deps/build.jl`  
`-rw-r--r-- 1 xiaoqihu tug 3309 May 16 15:55 build.jl`

How can I solve this problem?

Thank you!

The backtrace is missing, try running `julia ~/.julia/v0.6/LLVM/deps/build.jl` directly to see if there’s more information. I suspect an issue like [https://github.com/JuliaGPU/CUDAapi.jl/pull/9](https://github.com/JuliaGPU/CUDAapi.jl/pull/9)

I think you are right. Error happened in the same place

```julia

OK, shouldn’t be too hard to fix. Please file an issue on LLVM.jl. Also note that this codepath has been removed on latest LLVM for Julia 0.7.

Thank you much for all the information. Issue filed on LLVM.
