      "message": "Malloc debug rewrite.\n\nThe major components of the rewrite:\n\n- Completely remove the qemu shared library code. Nobody was using it\n  and it appears to have broken at some point.\n- Adds the ability to enable/disable different options independently.\n- Adds a new option that can enable the backtrace on alloc/free when\n  a process gets a specific signal.\n- Adds a new way to enable malloc debug. If a special property is\n  set, and the process has an environment variable set, then debug\n  malloc will be enabled. This allows something that might be\n  a derivative of app_process to be started with an environment variable\n  being enabled.\n- get_malloc_leak_info() used to return one element for each pointer that\n  had the exact same backtrace. The new version returns information for\n  every one of the pointers with same backtrace. It turns out ddms already\n  automatically coalesces these, so the old method simply hid the fact\n  that there where multiple pointers with the same amount of backtrace.\n- Moved all of the malloc debug specific code into the library.\n  Nothing related to the malloc debug data structures remains in libc.\n- Removed the calls to the debug malloc cleanup routine. Instead, I\n  added an atexit call with the debug malloc cleanup routine. This gets\n  around most problems related to the timing of doing the cleanup.\n\nThe new properties and environment variables:\n\nlibc.debug.malloc.options\n  Set by option name (such as \"backtrace\"). Setting this to a bad value\n  will cause a usage statement to be printed to the log.\n\nlibc.debug.malloc.program\n  Same as before. If this is set, then only the program named will\n  be launched with malloc debug enabled. This is not a complete match,\n  but if any part of the property is in the program name, malloc debug is\n  enabled.\n\nlibc.debug.malloc.env_enabled\n  If set, then malloc debug is only enabled if the running process has the\n  environment variable LIBC_DEBUG_MALLOC_ENABLE set.\n\nBug: 19145921\n\nChange-Id: I7b0e58cc85cc6d4118173fe1f8627a391b64c0d7\n"
