It is written in C, and works on Mac,\nLinux and Windows.\n\nThis package provides the following features:\n\n- Array indexing errors (positive) trigger crashes, because allocations are\n  aligned as closely as possible up to an inaccessible virtual memory page.\n\n- Using memory after freeing it triggers a crash most of the time.\n\n- Double frees are detected most of the time.\n\n- Unsynchronized multi-threaded access is detected.\n\nTo improve the chances of crashing on use-after-free or double frees,\nincrease the size of the heap. Freed blocks are kept on an \"observation\nlist\" for as long as possible to flush out these error classes, but it will\neventually be reused.\n\nThis heap is terribly slow, and wastes tons of memory. You only want to use\nit to track down memory errors. One neat way of doing that is to provide a\nheap interface that can dynamically switch to this heap, maybe with a\nconfiguration option. You can then hunt for memory errors without recompiling.\n\nLicense\n-----------------------------------------------------------------------------\nCopyright (c) 2014, Insomniac Games\nAll rights reserved.\n\nRedistribution and use in source and binary forms, with or without\nmodification, are permitted provided that the following conditions are met:\n\nRedistributions of source code must retain the above copyright notice, this\nlist of conditions and the following disclaimer.\n\nRedistributions in binary form must reproduce the above copyright notice, this\nlist of conditions and the following disclaimer in the documentation and/or\nother materials provided with the distribution.\n\nTHIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS \"AS IS\" AND\nANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED\nWARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE\nDISCLAIMED.
