Ricardo Barreira 5e308f9056 Fix undefined behavior in FreeStackWinding ... Fix subtraction of unrelated pointers and integer overflow in FreeStackWinding (both are undefined behavior). In rare cases "i" would non-deterministically be between 0 and 2 even though the pointers were in unrelated addresses, which caused a spurious free of one of the three windings - eventually the real free would happen, be detected as a double free and an exit(1) would ensue. Example contents of w and stack->windings that triggered this in a test: 0xa9251c0 0x7f440a924f78 Checking for pointer equality makes the behavior defined and correct: http://port70.net/~nsz/c/c99/n1256.html#6.5.9		2017-10-31 13:05:32 +00:00
