Failed to precompile

Since yesterday:

What's the rest of the information for reproducing it?

What about on 1.8.5? What's the error message?

On 1.8.5?

[ValentinKaisermayer]

Sry, I don't have that installed right now.

[ChrisRackauckas]

Can you try it? As a patch release it has bugfixes to Base and the compiler.

[svretina]

I had a similar issue but without an error since it would close the terminal completely when I tried to precompile NonlinearSolve. Installing and precompiling with julia-1.8.5 solved the issue for me.

It also happens with Julia v1.7.3 (the latest release of v1.7, which we use for CI with Trixi.jl):

[ChrisRackauckas]

Interesting, it doesn't give an error message? What happens if you using NonlinearSolve?

It sounds like it's something that was fixed in later versions of Julia so I'll have to boot up v1.7.3 to reproduce. But that has a big startup time on my current laptop and I'm currently at a hackathon (and as described in https://discourse.julialang.org/t/julia-1-9-beta3-is-much-slower-for-first-time-users/93429/24 this laptop is not for programming haha) so if someone could post the error message I can try a few things.

Or if someone could just try removing something from the snoop precompilation and see if that fixes it that could be good.

Continuing the post above with the output on Julia v1.7.3:

It comes with a huge increase of RAM usage - so much that it starts swapping, slows down everything considerably, and nearly runs out of space...

[ChrisRackauckas]

Try removing TrustRegion from precompilation. Something seems bugged with its precompilation with Float32 (that's being fixed in the other PR)

[ranocha]

Seems to be fixed already on master (commit e1c35f5) - at least for Julia v1.7.3.

[ChrisRackauckas]

Okay that makes sense, no wonder I was having trouble reproducing. If someone could just do this last step (#132 (comment)) then we should tag all of the Float32 type fixes.
