Check the version summaries. Think it was Julia 171 or something. There's lots of bugs like that that crop up every other release.

Segfaults happen all the time with FFI. But yea OOM is a killer. Julia runtime guzzles RAM, but pkg add any of the sciml stuff and watch your RAM explode. Doesn't take much data to lose a half hour of your life installing a package...

The RAM usage is because precompilation runs in parallel. If you have like 16 threads going then yes it'll parallelize that over 16 times. But we have never seen a half hour package install, can you share the info to reproduce it?

On my decade old laptop `using Plots` (precompilation) takes a couple of minutes. Not half an hour but it may feel like that if someone is used to Python (or R) where imports are instantaneous. Though I think GP meant takes that much due to OOMs which may result in frozen or slow system.

A couple of minutes is expected. Even R and Python packages have to run the build processes for the associated C and Fortran codes, and those take similar time (or more for many packages). However, if a Julia package is precompiling for more than half an hour, that's not expected and I'd like to see a reproducer for this so we can fix it.

See my above comment for clarification

It's not a half hour package install. It's a half hour of loading everything back in to get to where you were because the runtime dropped sorry for the lack of clarity. But yea, it's real easy for pkg installs to oom people.
