title: What is the meaning of 0xdeadcab1 fault address
body: <p>I have observed this value in the r3 or x8 register (on ARM) a handful of times when crashing in native code on Android. The crash is always caused by <code>signal 11 (SIGSEGV), code 1 (SEGV_MAPERR)</code>. I was wondering if the specific value <code>0xdeadcab1</code> offers any additional information (like <code>0xdeadbaad</code> indicates a heap corruption) or is it synonymous with <code>SIGSEGV</code>/<code>SEGV_MAPERR</code>?</p>
