Homebrew Is there a valgrind-esque app for NDS?

[imgod22222]

I'm taking a C & Unix course this semester, and looking back @ NDS Dev, I was mostly curious: Is there an app for the NDS programmer to check if they have memory leaks/memory errors?

Thanks. I doubt the compilier has this functionality, so I wanted to ask. Also wanted to ask if there's a useful debugger like gdb (but I assume that a gdb replica is built-into emus).
