     8 // When running with AddressSanitizer, we need to explicitely set some
     9 // options specific to our codebase to prevent errors during runtime.
    10 // 
    11 // Currently, these are:
    12 //
    13 //   allow_user_segv_handler=1 - Tell ASan to allow our code to use its
    14 //   own SIGSEGV handlers. This is required by ASM.js internally.
    15 //
    16 //   alloc_dealloc_mismatch=0 - Disable alloc-dealloc mismatch checking
    17 //   in ASan. This is required because we define our own new/delete
    18 //   operators that are backed by malloc/free. If one of them gets inlined
    19 //   while the other doesn't, ASan will report false positives.
