Hi Everyone,

I am trying to locate an option to enable extra checking for debug
builds, like checked iterators and range checking.

I found a few configure options for mallocs at
https://sourceware.org/newlib/README but I was hoping for something
more.

Does Newlib have one? If so, then what is it?

Thanks in advance.
