+// This testcase is a snippet that did not compile correctly under
+// pre-release 2.10.x. The relevant discussion around it can be
+// found at:
+// https://groups.google.com/forum/?fromgroups#!topic/scala-internals/qcyTjk8euUI[1-25]
+//
+// The reason it did not compile is related to the fact that ICode
+// ops did not correctly define the stack entries they consumed and
+// the dead code elimination phase was unable to correctly reconstruct
+// the stack after code elimination.
+//
+// Originally, this did not compile, but I included it in the run
+// tests because this was ASM-dependand and did not happen for GenJVM.
+//
+// Thus, we run the code and force the loading of class B -- if the
+// bytecode is incorrect, it will fail the test.
