+// When First and Second are static frameworks with caches, this test fails due to bad cache isolation:
+// Caches included into both frameworks have 'ktypew' globals (with same name, hidden visibility and common linkage)
+// for writable part of this "unexposed stdlib class" TypeInfo.
+// ld ignores hidden visibility and merges common globals, so two independent frameworks happen to share
+// the same global instead of two different globals. Things go wrong at runtime then: this writable TypeInfo part
+// is used to store Obj-C class for this Kotlin class. So after the first object is obtained in Swift, both TypeInfos
+// have its class, and the second object is wrong then.
