I think those interceptors means that we define the same name functions as libc, like memset, and preload it before libc, so the instrumented code call the asan memset not the libc memset. So the preload decides whether call asan memset or not, and Gcc Asan only preload the libasan.so for the instrumented lib not using LD_PRELOAD for the entire process, so a little confused, am I wrong? 在 2014年8月7日星期四UTC+8下午7时21分07秒，Yuri Gribov写道： > > > I used Gcc Asan recomplied only one shared lib, and I think the > interceptors > > only works for this lib, why the other could call those asan > interceptors? > > No-no, that's not how interceptors work on Linux.
