My julia nightly was a few days old, it seems this was from just before the multithreaded GC loop: ``` $ /home/datastore/lorenz/software/julia/jv/julia/usr/bin/julia _ _ _ _(_)_ | Documentation: https://docs.julialang.org (_)...

And here is an example from the CI on 26.04.: https://github.com/oscar-system/Oscar.jl/actions/runs/4807011160/jobs/8555232756

_edit:_ Singular crash backtraces moved to oscar-system/Singular.jl#641

Another night, another crash, this time with 1.9.0-rc3 (official binary for linux x64). Out of the 10 doctest loops I ran only one crashed with a core file, but the...

With the debug output I also used for #2341 it turns out that this is triggered in the `all_character_table_names` doctest: ``` page: /home/datastore/lorenz/software/julia/Oscar.jl/src/Groups/group_characters.jl:380-395 Segmentation fault (core dumped) ``` Apart from...

Preliminary result of the somewhat tedious bisect: ``` # first bad commit: [1f94d2e819d5a7e61f5556af70d49c7f61635b43] Only add big objarray to remset once (#49315) ``` I.e. it started with the same change (https://github.com/JuliaLang/julia/pull/49315)...

I haven't looked at the doctest crashes recently but there are still crashes from time to time (as usual for the doctests without any helpful output ....): https://github.com/oscar-system/Oscar.jl/actions/runs/5552727025/jobs/10140416762 https://github.com/oscar-system/Oscar.jl/actions/runs/5584752881/jobs/10206572309 Both...

Documenter is using IOCapture to redirect the output, like this: ``` julia> c = IOCapture.capture() do unsafe_load(Ptr{Any}(0)) end; Segmentation fault ~ $ ``` Maybe we can switch to a custom...

I tried `rr` but that doesn't seem to be possible in github actions due to linux kernel restrictions. A [patched](https://github.com/oscar-system/Oscar.jl/commit/0614ae457d477021000bab77e3a483d201773a34#diff-a1e73b7513a687e97da96a9dd66b36c387aafe33bae2e3de2cf358bcd947c77d) Documenter versions seems to be working, crashes so far: -...

Just after you wrote this the doctests [here](https://github.com/oscar-system/Oscar.jl/actions/runs/5964602260/job/16180184142?pr=2734#step:8:11) crashed for julia 1.9 (on ubuntu) with a segfault (and as usual no other information).
