Subject: [PATCH] Zero fill the allocated memory for a new ACE
Fixes a bug inside a call to `verify_ace_flag`. When a flag string (char*)
passed as a first parameter is "0x0", the final flag value (the second
parameter - the value of a pointer to uint8_t) is not modified at all
and contains the original memory contents == trash.
