Statement memoization was removed in r348822 because it was noticed to cause memory corruption. This was happening because a reference to an object in a DenseMap was used after being invalidated by inserting a new key into the map. This test case crashes reliably under ASan (i.e., when Clang is built with -DLLVM_USE_SANITIZER="Address") on at least some machines before r348822 and doesn't crash after it. llvm-svn: 349000
