Description
(Filed this first in Julia issues [51249](https://github.com/JuliaLang/julia/issues/51249), but got directed here. My gut feeling was that Julia gives invalid memory to FFTW)
Julia 1.9.3 installed from Generic linux package on Ubuntu 22.04 system.

I get a crash when using the below code as a module with `using Test`, but not if I load the source directly in REPL `include("Test.jl")`.
Test.jl code below
view in `fft_out = fft(view(A, :, 1))` is not actually needed, also `fft_plan*A[:,1]` crashes. I just used the view when hit this the first time)
```
module Test
using FFTW
A = randn(ComplexF64, 128, 10)
fft_out = fft(view(A, :, 1))
fft_plan = plan_fft(zeros(ComplexF64, 128))
# This doesn't crash when loading the module
fft_out = fft_plan*view(A, :, 1)
function test()
A = randn(ComplexF64, 128, 10)
# this crashes
f = fft_plan*view(A, :, 1)
# this doesn't crash either loaded from REPL or as module
# f = fft(view(A, :, 1))
end
end # module Test
```
I.e. below does not crash
```
julia> include("Test.jl")
Main.Test
julia> Test.test()
128-element Vector{ComplexF64}:

```
but this crashes
```
