Update:

**Julia not being able to call `juliac`-compiled library** : See the progress on the issue linked above:

> This is a known limitation currently, as each system image thinks it’s the only one that should be loaded. Soon we will have a workaround for this by allowing you to give a library its own private copy of the julia runtime.

**`juliac` vs. binding partitions** : I run into the same problems as reported here: [Segmentation fault in executable after compilation with juliac including --trim --experimental arguments - General Usage - Julia Programming Language](https://discourse.julialang.org/t/segmentation-fault-in-executable-after-compilation-with-juliac-including-trim-experimental-arguments/125303).

- As long as I have a simple example that does not rely on other packages (no `using` or `import` statements), I can use `--experimental --trim`.
- As soon as I rely on other packages (`JSON.jl` in my PoC), I cannot use `--trim` anymore. Errors similar to the ones reported in the referenced thread occur.
- This seems to be due to a regression between the two experimental features “_trimming during binary generation_” and “_binding partitions_”.
- I can compile and successfully run (on Windows and in a Docker container under `ubuntu:latest`) examples relying on other packages, just without `--trim` and thus a ~200 MB instead of 1.8 MB library. But for my PoC, that’s OK for the moment.
