| // 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. |
