"People experiencing sound corruption or other strange bugs on
recent distribution releases may want to have a look at this Fedora
bugzilla entry. It seems that the glibc folks changed the
implementation of memcpy() to one which, in theory, is more highly
optimized for current processors. Unfortunately, that change
exposes bugs in code where developers ignored the requirement that
the source and destination arrays passed to memcpy() cannot
overlap. Various workarounds have been posted, and the thread
includes some choice comments from Linus Torvalds, but the problem
has been marked "not a bug." So we may see more than the usual
number of problems until all the projects with sloppy mempcy() use
get fixed. (Thanks to Sitsofe Wheeler)."
