// When running with AddressSanitizer, we need to explicitely set some
// options specific to our codebase to prevent errors during runtime.
// 
// 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.
