#ifndef _MSC_VER // Not supported by clang-cl yet
// When running with AddressSanitizer, we need to explicitly set some
// options specific to our codebase to prevent errors during runtime.
// To override these, set the ASAN_OPTIONS environment variable.
//
// Currently, these are:
//
// allow_user_segv_handler=1 - Tell ASan to allow our code to use its
// own SIGSEGV handlers. This is required by ASM.js internally.
//
// alloc_dealloc_mismatch=0 - Disable alloc-dealloc mismatch checking
// in ASan. This is required because we define our own new/delete
// operators that are backed by malloc/free. If one of them gets inlined
// while the other doesn't, ASan will report false positives.
//
// detect_leaks=0 - Disable LeakSanitizer. This is required because
// otherwise leak checking will be enabled for various building and
// testing executables where we don't care much about leaks. Enabling
// this will also likely require setting LSAN_OPTIONS with a suppression
// file, as in build/sanitizers/lsan_suppressions.txt.
