As found with -fsanitize=address by HJ, but it also shows up with
valgrind. The fix for the PR is the change in scanner.c; I think the
patch is rather obvious.
The change in error.c is due to:
if (c1 == c2)
c2 += 1;
which could lead to an out-of-bounds condition is "c1" is already at
the last character - then one exceeds the bound for c2.
Build and tested on x86-64-linux with no new failures.*
OK for the trunk?
