It is just what my gut feeling expected: `unsigned char' uncleanliness.
Unfortunately, the problem is in libc _and_ the <ctype.h> header, which
_should_ have been pulled up to 1.3.2 release, but apparently was not.
The difference lies in the definition of the ctype macros in <ctype.h>:
#define isalpha(c) ((int)((_ctype_ + 1)[c] & (_U|_L))) /* 1.3.x */
#define isalpha(c) ((int)((_ctype_ + 1)[(int)(c)] & (_U|_L))) /* current */
This subtle difference threw off sed (and, incidentally, anything using
<ctype.h> working with high-ASCII characters).
I've put a temporary "hotfix" version of sed up at:
ftp://ftp.netbsd.org/pub/NetBSD/arch/arm32/sed_fix
The proper fix is to update libc.so.12.20 and /usr/include/ctype.h. I shall
pull down a tree and recompile libc, making it available with a fixed
ctype.h shortly. If you don't download the hacked sed above, replacing libc
will also solve the problem. Watch this space for announcements.
