I reproduced your crash last week on a Niagara3 system, therefore I
don't think it is dependent upon the memcpy implementation.

If you are still convinced it is some memcpy issue :-) I can only
suggest that you check those buffer pointers passed to memcpy, if
(given the size) they overlap at all, that would be a bug.  You can't
use memcpy() for overlapping buffers, one must use memmove() instead.
