1 | // Test for __lsan_do_leak_check(). We test it by making the leak check run |
2 | // before global destructors, which also tests compatibility with HeapChecker's | |
3 | // "normal" mode (LSan runs in "strict" mode by default). | |
4 | // RUN: LSAN_BASE="use_stacks=0:use_registers=0" | |
5 | // RUN: %clangxx_lsan %s -o %t | |

6 | // RUN: %env_lsan_opts=$LSAN_BASE not %run %t 2>&1 | FileCheck --check-prefix=CHECK-strict %s |
7 | // RUN: %env_lsan_opts=$LSAN_BASE not %run %t foo 2>&1 | FileCheck --check-prefix=CHECK-normal %s | |
