Reaches `EXCEPTION_ACCESS_VIOLATION`

[charleskawczynski]

I recently ran into the error:

Julia Version 1.10.5
Commit 6f3fdf7b36 (2024-08-27 14:19 UTC)
Build Info:
  Official https://julialang.org/ release
Platform Info:
  OS: Windows (x86_64-w64-mingw32)
  CPU: 8 × Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz
  WORD_SIZE: 64
  LIBM: libopenlibm
  LLVM: libLLVM-15.0.7 (ORCJIT, skylake)
Threads: 1 default, 0 interactive, 1 GC (on 8 virtual cores)

Here is a reproducer:

# git clone https://github.com/CliMA/ClimaAtmos.jl
# cd ClimaAtmos.jl/
# git checkout b1c50ea69a72231c3e74a2489670273b782b3ead
# julia --project=examples

using SnoopCompileCore
ENV["CLIMACOMMS_DEVICE"]="CPU";
tinf = @snoop_inference begin
  empty!(ARGS);
  push!(ARGS, "--config_file", "config/model_configs/diagnostic_edmfx_trmm_stretched_box.yml");
  push!(ARGS, "--job_id", "diagnostic_edmfx_trmm_stretched_box");
  include("examples/hybrid/driver.jl")
end;

using SnoopCompile, FlameGraphs, ProfileView
fg = flamegraph(tinf)
ProfileView.view(fg)

Ah, after checking out that branch, you'll need to modify examples/hybrid/driver.jl to:

redirect_stderr(IOContext(stderr, :stacktrace_types_limited => Ref(false)))
import ClimaComms
ClimaComms.@import_required_backends
import ClimaAtmos as CA
import Random
Random.seed!(1234)
if !(@isdefined config)
    (; config_file, job_id) = CA.commandline_kwargs()
    config = CA.AtmosConfig(config_file; job_id)
end
simulation = CA.get_simulation(config)
(; integrator) = simulation
import SciMLBase
SciMLBase.step!(integrator)

FWIW, I'm pretty sure that I only observed this on my windows machine.

Looks like something deep inside GTK4. What's the output of the following?

using Pkg
Pkg.status(["GTK4_jll","Pango_jll","Cairo_jll"];mode=PKGMODE_MANIFEST)

[charleskawczynski]

I just got around to trying this out:

julia> using Pkg

julia> Pkg.status(["GTK4_jll","Pango_jll","Cairo_jll"];mode=PKGMODE_MANIFEST)
Status `C:\dev\ClimaAtmos.jl\examples\Manifest.toml`
  [83423d85] Cairo_jll v1.18.0+2
  [36c8627f] Pango_jll v1.54.1+0

[jwahlstrand]

Thanks, those are the latest versions. It's confusing that Fontconfig is being called on Windows. I had thought that in recent versions of Pango_jll/Cairo_jll on Windows that the native font handling mechanism would be used instead. I'll try your reproducer when I have time.

[charleskawczynski]

Also, just a heads up: it takes a little while to run-- I think somewhere inside 30 minutes (basically all compilation time)
