michael@0: // Currently, these are:
michael@0: //
michael@0: //   allow_user_segv_handler=1 - Tell ASan to allow our code to use its
michael@0: //   own SIGSEGV handlers. This is required by ASM.js internally.
michael@0: //
michael@0: //   alloc_dealloc_mismatch=0 - Disable alloc-dealloc mismatch checking
michael@0: //   in ASan. This is required because we define our own new/delete
michael@0: //   operators that are backed by malloc/free. If one of them gets inlined
michael@0: //   while the other doesn't, ASan will report false positives.
