1 // Ensure that operator new/delete are still replaceable using static-libsan.
2 
3 // FIXME: Weak symbols aren't supported on Windows, although some code in
4 // compiler-rt already exists to solve this problem. We should probably define
5 // the new/delete interceptors as "weak" using those workarounds as well.
6 // UNSUPPORTED: target={{.*windows.*}}
7 
8 // darwin only supports `shared-libsan`.
9 // REQUIRES: asan-static-runtime
10 
11 // RUN: %clangxx %s -o %t -fsanitize=address -static-libsan && not %run %t 2>&1 | FileCheck %s
