Track C

Address Sanitizer (ASAN) and Leak Sanitizer (LSAN) have a lot of options and additional functions which sometimes could be used not only for detecting memory errors and leaks.

This talk will cover LSAN internals (combined memory manager, interceptors, garbage collector which does not collects garbage, why LSAN does not work with gdb), ASAN and LSAN public interface, how to profile memory usage via ASAN or LSAN, obtaining about objects metadata, memory manager statistics and useful functions which could be used from gdb.

Also we'll try to improve LSAN diagnostic output via using non public LSAN API.
