Research direction
Investigate how core files are generated in the YugabyteDB build when compiled with ASAN or TSAN. Look at the sanitizer flags used and check if default core file generation is suppressed. Compare with the documentation on sanitizer common flags. Propose a fix to enable core dumps while preserving sanitizer functionality.
