Author: nmusgrave Date: Tue Sep 8 11:38:17 2015 New Revision: 247025 URL: http://llvm.org/viewvc/llvm-project?rev=247025&view=rev Log: Failing test highlighting no poisoning if dtor undeclared.
Summary: If class or struct has not declared a destructor, no destructor is emitted, and members are not poisoned after destruction. This case highlights bug in current implementation of use-after-dtor poisoning (detailed in https://github.com/google/sanitizers/issues/596). Reviewers: eugenis, kcc Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D12616 Only check simplest object for existence of sanitizing callback. Rename test.
