Hi I have been encountering this problem for both Julia 1.5.3 and 1.5, under both Julia Pro and VS Code.  
Whenever I ran codes in Julia, there will always be some strange messages in the terminal, like

```julia

There are hundreds of lines or such messages each time and I have to wait for about 2 minutes before the code could run normally. Is there anyone who knows how to solve this? I have tried Julia 1.0 and 1.2 and there is no such issue. My system is Windows 10.

Does this also happen in the REPL? What about using the normal Julia binaries together with Atom, rather than JuliaPro?

It’s almost like a debugger is attached to the Julia process. How did you obtain Julia?

Sorry just to confirm, when you download the Julia 1.5.3 executable from the Julia website, do a clean install on Windows, open the REPL (by just double clicking on the Julia icon on your desktop), and run

```julia
julia> 2+2

```

you get back all of those messages above, instead of just `4`?

In Powershell, what is the output of `Get-ChildItem env:` . I’m trying to see if there is anything in your environment that may be causing this.

You might want to delete your `%USERPROFILE%\.julia` folder or move it somewhere else as a test to see if it is anything in there.

You mentioned Julia Pro. Maybe try standard Julia: [Download Julia](https://julialang.org/downloads/)

Hi Nilshg,  
The result for both Julia 1.5.3 and Julia with VSCODE for the command is 4.  
It seems that the error only happens when I run self-coded functions.

You seem to have many versions of Julia installed. There’s JuliaPro, Julia 1.5.0\_2 and Julia 1.5.3.

Just so we’re clear, also give us the output of `versioninfo()`

Do you have a `.julia\startup.jl` ?

Does this happen with simple self-coded functions like `f(x) = x*x` ? Or particular ones?

It seems your self-coded functions seems to be running out of memory. Can you share with us a minimum working example of a self-coded function that causes these issues?

Hi the error does not occur for functions like f(x) = x\*x.  
There is no complicated calculation in the functions. And I can get the results from these functions after the end of the messages.  
For Julia 1.0 and 1.2 versions, I do not encounter such issues either.

I think we really need a Minimum Working Example (MWE) that demonstrates the issue to progress further. Could you try to isolate what lines in your function are causing the issue?
