On 1.11, Chairmarks works fine. On 1.12, it segfaults. The strings
"@inbounds"and"unsafe"do not appear in thesrcdirectory and I don't do anything particularly internal that I know of. IMO, the funkeyest code is here: https://github.com/LilithHafner/Chairmarks.jl/blob/80e84d0ba90fcac61959d1f992e034f5445bf4cd/src/benchmarking.jl#L115-L165.Tagging GC at a guess because it appears in the segfault stack trace, but it could certianly be due to a non-gc issue.
