Kostya Serebryany <kcc at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |INVALID --- Comment #1 from Kostya Serebryany <kcc at gcc dot gnu.org> --- - don't add -lsan. -fsanitize=address is all you need. - please provide more details. - check if lsan works for you on a simple synthetic test case, e.g. grab some from https://github.com/llvm-mirror/compiler-rt/tree/master/test/lsan/TestCases - does the lsan in fresh clang work for you? Since the bug report is not actionable at this point I am closing it. Please reopen when the above bullets are checked.
