-+# In ASAN builds, PartitionAlloc-Everywhere is disabled, meaning malloc() and
-+# friends in C++ do not go to PartitionAlloc. So we also don't point the Rust
-+# allocation functions at PartitionAlloc. Generally, this means we just direct
-+# them to the Standard Library's allocator.
-+#
-+# However, on Windows the Standard Library uses HeapAlloc() and Windows ASAN
-+# does *not* hook that method, so ASAN does not get to hear about allocations
-+# made in Rust. To resolve this, we redirect allocation to _aligned_malloc
-+# which Windows ASAN *does* hook.
-+#
-+# Note that there is a runtime option to make ASAN hook HeapAlloc() but
-+# enabling it breaks Win32 APIs like CreateProcess:
