Hello! I am trying out a function I have written to implement the power method. I am filling a CSRMatrix (a type created in the project I am working on) and then running my function with that matrix. I have no problems when I just fill the matrix OR when I just run the function on an unfilled matrix. However, if I try to fill the matrix and use my function, the Julia REPL crashes and the error in the attached screenshot appears.
From some googling, it seems like the issue has to do with a file being read/written to, but I do not know how to start with fixing it. Does anyone have any ideas?
I appreciate any help, thanks!

139 usually indicates a segfault. Try the instructions [here](https://www.julia-vscode.org/docs/stable/faq/#The-integrated-REPL-closes-when-the-Julia-process-crashes.-How-do-I-get-more-information-on-what's-going-on?) to hopefully get a stacktrace.

Thank you for the response. I tried the tmux approach, but the Julia REPL still crashed (the bash terminal stayed open, but no error messages appeared there) so I could not see the error message. Does that mean I didn’t use tmux properly?

Try the second approach and post the output here. It’s definitely possible, but rare, for Julia to die without any output. In that case, I’d recommend trying to repro the issue in a normal REPL (without the VS Code integration loaded) and run Julia through gdb or RR.

Could you also run `versioninfo()`and post the results?

Does it only happen in VSCode and not when you run the same code in an (external) REPL? You could try running julia with `--check-bounds=yes` to check for out of bounds indexing.

When I run it in an external REPL, the seg fault still happens, but this time I can see the error message:

So is the error originating with the localApply function that I am using in tryPower.jl?

The `@inbounds` here may be the culprit

Do give Fredrik’s suggestion of running Julia with `--check-inbounds=yes` a go.

When I run:
```
./tryPower.jl --check-inbounds=yes
```
I get errors that have not come up before (
```
./tryPower.jl: line 1: using: command not found
./tryPower.jl: line 5: syntax error near unexpected token `A::Matrix{},'
./tryPower.jl: line 5: `function power(A::Matrix{}, niter::Integer, tol::Float64)'

). Perhaps I am not running this correctly?

Ah, my bad, that’s a typo. It should be something like `julia --check-bounds=yes ./tryPower.jl`.

Ok, you don’t have julia on your path. Use the full path from that error message in your screenshot (`/Applications/...`) instead of `julia` in that code snippet.

```julia
/Applications/Julia-1.7.app/Contents/Resources/julia/bin/julia --check-bounds=yes ./tryPower.jl

should be the right one.

Probably best if you start a REPL session with
```julia
/Applications/Julia-1.7.app/Contents/Resources/julia/bin/julia --check-bounds=yes
```
and then activate the right project manually, after which `include("tryPower.jl")` should do the right thing.

The line you mentioned above is in fact where the error is originating.
```
@inbounds sum += val*rawX[ind, vect]
LoadError: BoundsError: attempt to access 2×1 Matrix{Float32} at index [0, 1]

Thank you for your help! I will see what I can do to fix this invalid indexing.
