;; Regression repro of PGM_BASE::HandleException (KiCad) — the case-6 shape (a cpp catch nested in an
;; outer try's catch_all cleanup pad) WITH an intervening block in that cleanup that the cpp arm
;; br's to. LLVM emits this for `try{} catch(A&) catch(B&) catch(...)`: the outer try has only a
;; catch_all (destructor cleanup), inside which it (rethrow)s into a nested try whose cpp catch does
;; the __cxa type dispatch and, when done, (br)s OUT to a block ($blk) sitting between the escape
;; target and the arm. Hoisting that arm to the dispatch section orphaned the br — "all break targets
;; must be valid, on (br $blk)". cpp tag = single i32.
(module
 (tag $cpp (param i32))

 ;; Exception path: outer body throws cpp(1); the catch_all reclassifies via (rethrow $outer) inside
 ;; (block $blk); the nested cpp arm handles it (r := 42) then (br $blk) to finish.  expect 42.
