Tracking Issue for spurious mingw CI failures

[jieyouxu]

The spurious mingw failures might be related to #127883, but for the purpose of tracking, we should delineate the two general categories separately to avoid conflating them.

Please feel free to update specific classifications of kinds of spurious mingw failures.

Known problems

• CI: spurious error building LLVM on mingw: ranlib.exe: could not create temporary file whilst writing archive: no more archived files #108227

Misc

Label: CI-spurious-fail-mingw CI spurious failure: target env mingw

I guess it is possible something is pushing close to the limits of the stack and just sometimes it tips over the edge. Though I'm not sure why that would be.
