--- Comment #6 from Michel Morin <mimomorin at gmail dot com> --- True. Detectable is not correct — that's "maybe-detectable" at most, and the bug is not silent. In a code that I checked, the buggy code (`std::cout << NullCharPtr;`) is the last printing call to std::cout, so I failed to see the side-effect. The patchlet using `_GLIBCXX_DEBUG_PEDASSERT` works fine. Actually I would like `_GLIBCXX_DEBUG_ASSERT` (because I've been using `_GLIBCXX_DEBUG` but never `_GLIBCXX_DEBUG_PEDANTIC`), but I guess using `_GLIBCXX_DEBUG_PEDASSERT` rather than `_GLIBCXX_DEBUG_ASSERT` in this case is a delibarate choice.
