+Subject: [PATCH 1/2] Ensure stack in `ThirBuildCx::mirror_exprs`
+
+This solve a stack overflow found on Fedora s390x when building
+`tests/ui/parser/survive-peano-lesson-queue.rs`. Note that the singular
+`mirror_expr` method already has this stack check, but in this case the
+plural method was the one recursing too deeply.
