1 Regression test for b/62237378 2 3 It was possible for the JVMTI class redefinition to encounter a use-after-free 4 bug if there had been an attempted redefinition that failed due to a 5 verification error in the same class loader. Actually encountering the bug 6 required that a later redefinition happen to get the same native pointer for its 7 dex-file as the failed redefinition. 8 9 Hitting this use-after-free can cause many strange outcomes, from CHECK failures 10 to segfaults to incorrect redefinition failures (for example on buggy builds 11 this test will fail a DCHECK on debug builds, segfault on x86_64 hosts and have 12 redefinition of LDexCacheSmash$Transform; erroneously fail with 13 JVMTI_ERROR_FAILS_VERIFICATION on 32 bit hosts). 14
