// 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.
