segfault after importing CSV and Images, PyPlot from a separate module

[MaxandreJ]

Hi,

I get the following segfault

signal (11): Segmentation fault: 11
in expression starting at /MyProjectDirectory/Test.jl:4
_platform_strcmp at /usr/lib/system/libsystem_platform.dylib (unknown line)

when I run /MyProjectDirectory/Test.jl which contains the code

push!(LOAD_PATH, "/MyProjectDirectory")
import CSV
using MyModule

that uses /MyProjectDirectory/MyModule.jl which contains the code

module MyModule
using Images
import PyPlot
end

I don't know if this is an issue to do with CSV, Images, PyPlot or Julia itself. This is a minimal working example. I'm using Julia 1.0.1 on MacOS Mojave. The segfault goes away if I don't load any one of these three packages. There is still a segfault if I start Julia with --check-bounds=yes.

I hope this can be resolved soon! Segfaults are frightening...

These are the versions of the packages in question + important dependencies

Images v0.16.0
PyCall v1.18.5+ #Master (https://github.com/JuliaPy/PyCall.jl.git)
PyPlot v2.6.3
CSV v0.4.1

I have also posted this issue on the PyPlot.jl github and the CSV.jl github.

Best,
Max

Can you replicate this without defining a package? I.e., on the REPL? (I can't, just by using the 3 packages.)

Hi @timholy and thank you for your answer!
No, there's no segfault if I just run

import CSV
using Images
import PyPlot

The segfault only happens in the case that I explain in the first post in this thread.

I am having this same problem when building Cairo (JuliaGraphics/Cairo.jl#271).

I think this can be some incompatibility between Julia and Mojave.

FWIW, I no longer see this by trying JuliaPy/PyPlot.jl#402 (comment) in Julia 1.6.0 with macOS BigSur
