Segfault during `eval` about julia HOT 7 OPEN

I think it would help with some more information.

from julia.

It sounds a bit like a call to Module() that the user isn't then properly gc-rooting (the proper way to make a module is with @eval(module Foo end), but the alternative constructor exists for power users in some cases)

from julia.

Yeah, but a minimal example is still sought after. If you cannot provide that, then one would need the actual code. Otherwise I believe it is quite hard to know what the actual issue is, no?

from julia.

Sadly, this is a private package, so I can't share the code itself, but the error happened when we were evaluating the code with ReTestItems which validates the files during Base.include here. The test file in question contained a single @testitem behind a @static check:

@static if get(VERSION.prerelease, 1, "") != "DEV"
    @testitem "JET error analysis TypeOrder package" begin
        ...
    end
end

We're using a patched Julia 1.10.2.
Please let me know what other information would be helpful to diagnose this.

Could it be #51267 ?

from julia.

From the backtrace, it looks to me like a search through module bindings segfaulted, which is different from #51267. I was wondering if #49556 perhaps unintentionally broke something and was hoping the backtrace might be enough to diagnose it.

Sadly, this does not happen deterministically, so we have little hope of getting an rr trace.

from julia.

We should use the @eval(module Foo end) style in ReTestItems, AFAIK.
We managed to get a core dump so we'll try to examine it with @kpamnany.
