Precompilation error with julia nightly

[lgoettgens]

We observe this on our Oscar.jl CI since some point last night.

The recompilation failure happened with Julia Version 1.13.0-DEV.650, Commit 7a87048e6d2 and still succeeded with Julia Version 1.13.0-DEV.646, Commit 8ac92910eb4. Thus, the problem was introduced somewhere in JuliaLang/julia@8ac9291...7a87048
My uneducated guess would be JuliaLang/julia#58131 by @vtjnash

That is a libcxxwrap error, not Julia. From searching the issue list, this seems to be a common problem requiring a rebuild https://github.com/JuliaInterop/libcxxwrap-julia/blob/3565a1afa4fa18c683bf02ec76f7b7d21b93bfcd/include/jlcxx/module.hpp#L1300

Thanks, I launched a rebuild for libcxxwrap-julia on Yggdrasil.
