1 | // Regression test for thread lifetime tracking. Thread data should be |
2 | // considered live during the thread's termination, at least until the | |
3 | // user-installed TSD destructors have finished running (since they may contain | |
4 | // additional cleanup tasks). LSan doesn't actually meet that goal 100%, but it | |
5 | // makes its best effort. | |
6 | // RUN: LSAN_BASE="report_objects=1:use_registers=0:use_stacks=0:use_globals=0" | |
7 | // RUN: %clangxx_lsan %s -o %t | |
8 | // RUN: LSAN_OPTIONS=$LSAN_BASE:use_tls=1 %run %t | |
9 | // RUN: LSAN_OPTIONS=$LSAN_BASE:use_tls=0 not %run %t 2>&1 | FileCheck %s | |
