+.. title:: clang-tidy - portability-std-allocator-const-t
+
+portability-std-allocator-const-t
+=================================
+
+Per C++ ``[allocator.requirements.general]``: "T is any cv-unqualified object
+type", ``std::allocator<const T>`` is undefined. Many standard containers use
+``std::allocator`` by default and therefore their ``const T`` instantiations are
+undefined.
+
+libstdc++ never supports ``std::allocator<const T>`` and containers using them.
+Since GCC 8.0 (`PR48101 <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=48101>`),
+there is a better diagnostic for some containers.
+
+.. code:: c++
+
+  std::deque<const int> deque; // error: static assertion failed: std::deque must have a non-const, non-volatile value_type
+  std::set<const int> set; // error: static assertion failed: std::set must have a non-const, non-volatile value_type
+  std::vector<int* const> vector; // error: static assertion failed: std::vector must have a non-const, non-volatile value_type
+
+However, code bases not compiled with libstdc++ may accrue such undefined usage.
+This check finds such code and prevents backsliding while clean-up is ongoing.
