Re: glibc detected *** free(): invalid pointer

["Bruce Korb" <bruce dot korb at gmail dot com>]

Though Petter R. will (eventually) find the cause of his problem via valgrind,
nevertheless it would, indeed, be extremely helpful if error messages like this
were to have some hint about where to look.  Google on "glibc" and
"invalid pointer" and you will see messages from many, many frustrated folks.
This message is awful. It needs to be enhanced with a hint about which
component of glibc stumbled on the issue so your customers can more readily
narrow the focus of their search.  This is the correct list for that.
Thank you - Bruce
