--- Comment #38 from Sergey Matveev <earthdok at google dot com> --- (In reply to Jakub Jelinek from comment #28) > Author: jakub > Date: Fri Nov 22 21:13:08 2013 > New Revision: 205290 It looks like you use dynamic linking by default. The last time I checked, leak detection (in both ASan and standalone LSan) didn't work 100% correctly with dynamic linking. Should be easy to fix by giving one of the interceptors a stronger visibility.
