On http://b/122082295 we had this abort: 12-27 15:29:31.237 10222 10814 10848 F libc : invalid pthread_t 0xb1907960 passed to libc This wasn't super helpful. We can do better. Now you get something like this instead: 03-27 02:34:58.754 25329 25329 W libc : invalid pthread_t (0) passed to pthread_join Test: adb shell crasher Bug: http://b/123255692 Change-Id: I1d545665a233308480cc3747ec3120e2b6de0453
