[LLVM8] Illegal intoptr llbm assertion during Plots.contour

[wforbes-pde]

I'm trying to use Plots.contour. I'm not entirely sure that my objects have the appropriate size/shape for contour.

x is Vector{Float64} with 513 elements
t is Vector{Float64} with 10001 elements
time_steps is 10001x513 Array{Float64,2}

using Plots
Plots.contour(x, t, time_steps)


Illegal inttoptr
​     %37 = ptrtoint double addrspace(13)* %36 to i64
Illegal inttoptr
      %56 = inttoptr i64 %55 to i8 addrspace(13)*

@wforbes-pde What is your versioninfo()? From the output it seem like you might be running Julia 1.4?

[wforbes-pde]

It appears that I am. I vaguely recall some preferred method of installing Julia where it would be easier to update.

julia> versioninfo()
Julia Version 1.4.1
Platform Info:
OS: Linux (x86_64-linux-gnu)
CPU: Intel(R) Core(TM) i7-9700 CPU @ 3.00GHz

LLVM: libLLVM-8.0.1 (ORCJIT, skylake)
Environment:
JULIA_EDITOR = atom -a
JULIA_NUM_THREADS = 8

Where did you get this copy of Julia? These kinds of issues tens to happen if somebody decided to ignore our LLVM patchset. Can you try an official release?

[vchuravy]

From the stacktrace I suspect it is: https://launchpad.net/ubuntu/+source/julia/1.4.1+dfsg-1

[vchuravy]

Duplicate of #37003 and https://bugs.launchpad.net/ubuntu/+source/julia/+bug/1891205

@wforbes-pde we recommend the official release at https://julialang.org/downloads/ to avoid these issues

[vchuravy]

Yeah I checked their build recipe... USE_SYSTEM_LLVM=1, will cause issues like this.

[wforbes-pde]

I ran

sudo apt-get install julia

[vchuravy]

Please comment on https://bugs.launchpad.net/ubuntu/+source/julia/+bug/1891205 to let the Ubuntu maintainers know that you run into issues.

[wforbes-pde]

Sure. Thanks for the quick response.
