Debug builds are usually much slower, but if you use C++ that's even
more slower since simple things like a container acces via []-operator
occur with a separate function call while debugging. With iterator
-debugging that's even slower. But this price is worth the advantage
that you can easily find bounds-problems with C++.

Sounds similar to Pixar's "Electric Fence" that Kaz mentioned earlier:

Depending on the performance impact this may or may not be a viable
solution to debug a rare production issue, but still nice to know it
exists.
