Thanks for the reply

I do compile often

I’ve changed the optimization level to 0 as described in here:

> [@Change Optimization Level in VS Code?](https://discourse.julialang.org/t/change-optimization-level-in-vs-code/48966/2):

> If you go to the extension settings of the Julia extension, you see on top “Additional Args”. Edit this in settings.json and change it, that it looks like: ..., "julia.additionalArgs": ["--optimize=0"], ..., Of course without the … lines and with your desired level 0,1,2 or 3.

I didn’t find much of a difference however
