view auto/endianness @ 6245:3cf25d33886a

Core: fixed segfault with null in wildcard hash names. A configuration like server { server_name .foo^@; } server { server_name .foo; } resulted in a segmentation fault during construction of server names hash. Reported by Markus Linnala. Found with afl-fuzz.
