[cfe-users] Disable Leak Sanitizer

[Alexey Samsonov]

Hi Jeffrey,

At one point we should go and document it on the wiki, for now I'll just
briefly outline options here:

There are multiple ways to disable LeakSanitizer:
1) source-level annotations (see <sanitizer/lsan_interface.h> header) -
mark specific objects as intentionally-leaked
2) link in
extern "C" int __lsan_is_turned_off() { return 1; }
into binary (see <sanitizer/lsan_interface.h>) you want to exclude from
leak detection.
3) pass ASAN_OPTIONS=detect_leaks=0 environment variable to disable leak
detection at run-time.
