Excellent bug report.

You don't say what sort of memory error you had so of course
i'll point my finger and say "hardware error" :)

Rsync 1.6.2 is so old i don't know when it was released.
1.6.4-1.6.7 appear to have been released in December 1997.
Our OLDNEWS file doesn't even go back that far.  There have
been so many fixes (some security) since then it isn't

The current released version is 2.5.7 protocol 26.  2.6.0 is
to be released very soon.
