[PATCH] malloc: Abort on heap corruption, without a backtrace [BZ #21754]

[Paul Eggert]

Thanks, I like the overall change too. One quibble:

> +  __libc_message (do_abort, "Fatal glibc error in malloc: %s\n", str);

This change to the message wording won't work well, as the user will see 
redundant text like "Fatal glibc error in malloc: malloc(): memory corruption 
(fast)". Also, the wording "glibc error" suggests that there must be a fault in 
glibc, whereas it's more likely that the fault is in the application. I suggest 
changing the above line to:

   __libc_message (do_abort, "%s\n", str);

This is simpler, and this way glibc will keep using the same wording that it's 
been using for a while.
