描述

In the spirit of #44895, displaying an AbstractArray subtype with unsigned indices can throw an OutOfMemory exception. The offending lines are https://github.com/JuliaLang/julia/blob/a3f710e2a35402bb7f7f96f874e6c696dfc911da/base/arrayshow.jl#L138-L141 The max(0, difference of unsigned) is obviously not safe.

研究方向: Investigate the lines 138-141 in base/arrayshow.jl referenced in the issue. Understand the logic of displaying array indices and ensure safe subtraction when indices are unsigned. Consider using max(0, Int(difference)) or a similar safe conversion. Review the linked issue #44895 for context.
