Hi All,

Apparently the 64 bit version of memcpy in the Fedora 14 glibc will do the
copy in the downwards rather than the usual upwards direction on some
processors. This has exposed bugs where the the source and destination
overlap in memory. Report and discussion can be found at fedora
I don't know that numpy has any problems of this sort but it is worth
keeping in mind.
