[PATCH] D32194: Turn symbolication on for ASan unit test.

[Aleksey Shlyapnikov via Phabricator via llvm-commits]

alekseyshl added a comment.

For the context, here's the test I used:

  #include <pthread.h>
  static void *PthreadExit(void *a) {
    pthread_exit(0);
    return 0;
  }
  int main(int argc, char** argv) {
    pthread_t t;
    pthread_create(&t, 0, PthreadExit, 0);
    pthread_join(t, 0);
    return 0;
  }

and here's the stack LSan reports on my ppc machine:

Direct leak of 56 byte(s) in 1 object(s) allocated from:

The similar env and test on x86 does not report any leaks.
