Benjamin Kramer	e550bbdf9d	[Lexer] Don't read out of bounds if a conflict marker is at the end of a file This can happen as we look for '<<<<' while scanning tokens but then expect '<<<<\n' to tell apart perforce from diff3 conflict markers. Just harden the pointer arithmetic. Found by libfuzzer + asan! llvm-svn: 265125	2016-04-01 09:58:45 +00:00

This can happen as we look for '<<<<' while scanning tokens but then expect
