commit b5524e95a1f8ddc920287b9092558a86c987d037 Author: Gergely Fürnstáhl <[email protected]> AuthorDate: Tue Mar 7 14:52:17 2023 +0100 IMPALA-11935: Generate core dumps if ASAN/TSAN/UBSAN built be tests crash By default, on 64-bit systems, programs built with sanitizers do not produce minidumps nor coredumps due to the shadow memory - which is used for house keeping - being huge and the generated dumps would be too big (~16TB). https://gcc.gnu.org/bugzilla//show_bug.cgi?id=89868 The shadow memory can be stripped on exit and the core dumps can be generated by setting the (T|A|UB)SAN_OPTIONS environment variable before running the program. https://stackoverflow.com/questions/42851670/how-to-generate-core-dump-on-addresssanitizer-error This can help investigating crashes in sanitized builds. Testing: - Locally injected an std::abort() to a test case, built it with TSAN and verified the creation of the core dump and gdb showed the correct stack frame.
