      "message": "Switch from getrlimit(RLIMIT_AS) to android_mallopt(M_SET_ALLOCATION_LIMIT_BYTES).\n\nThe RLIMIT_AS limit was introduced as a security mitigation, but it\nisn\u0027t exactly what the media processes want to control. It is also\nproblematic under sanitizers which allocate large amounts of address\nspace as shadow memory, and is especially problematic under shadow\ncall stack, which requires 16MB of address space per thread. Instead,\nuse the newly introduced android_mallopt(M_SET_ALLOCATION_LIMIT_BYTES)\nto control the allocator\u0027s memory limit directly.\n\nAlso remove ASAN/HWASAN/CFI specific hacks; they are no longer\nnecessary because these tools consume address space using mmap and\nnot the allocator, and remove the 64-bit pointer check before calling\n__scudo_set_rss_limit, since otherwise the limit would stop being\nenforced in 32-bit mode with Scudo.\n\nBug: 118642754\nChange-Id: Ie66128626976c0b04d5dafd455c375bbfdccc083\n"
