FWIW, I don't know if it is related to the problems that you mention, but I did
notice that the standard strncat function was a bit buggy when I was working on
a patch recently. According to the documentation, strncat is supposed to null-
terminate the destination. From the man page:

"... As with strcat(), the resulting string in dest is always null-terminated.

The strncat function in Syslinux wasn't null-terminating the destination though.
I think I was developing against 6.04-pre2.
