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 bugzilla<https://bugzilla.redhat.com/show_bug.cgi?id=638477>. I don't know that numpy has any problems of this sort but it is worth keeping in mind.
Chuck
