Segfault using PythonCall on Apple M1 with Julia 1.11.0-rc4 #563

Something isn't working

I have a very similar issue with the final julia 1.11.0. The segfault is very non-deterministic. It doesn't always happen and when it happens it doesn't always happen at the same point. Some backtraces look like this: Others like this: Running the same code with julia 1.10.4 doesn't have this issue. |

I also get seg faults, on linux, only on multithread, in applications which worked with julia 1.10 |

Fwiw, here's a somewhat self-contained example that reliably crashes for me within a handful of runs (but it's non-deterministic), see this repository. Its only dependencies are import QuadGK
using PythonCall
const camb = pyimport("camb")
const Pm = let
params = camb.set_params(H0=70)
params.set_matter_power(redshifts=0:.1:1.5, kmax=9.5)
res = camb.get_results(params)
power = res.get_matter_power_interpolator(nonlinear=false, k_hunit=false, hubble_units=false, extrap_kmax=1e6).P
(z, k) -> let
pyval = power(z, k)
pyconvert(Float64, pyval)
end
end
calculate_stuff = (R, z) -> let
θ = R/900.
integrand = lθ -> let
kl = lθ/((1+z) * R)
sqrt(lθ)*cos(lθ)*Pm(z, kl) / (θ*θ)
end
QuadGK.quadgk(integrand, 0, 50)[1]
end
zvalues = [0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7]
Rvalues = collect(.1:.2:7.0)
@info @. calculate_stuff(Rvalues, zvalues') |

Affects: PythonCall
Describe the bug
I got a segfault using PythonCall on GitHub CI for Apple M1.
https://github.com/JuliaIO/ZipArchives.jl/actions/runs/11219970406/job/31187122812?pr=82
This seems to be an intermittent issue.
Your system
