+// This is done as a partial fix for
+// https://github.com/gazebosim/gz-physics/issues/442. The issue seems like the
+// destructors for the concrete collision detectors get unloaded and deleted
+// from memory before the destructors run. When it's time to actually call the
+// destructors, a segfault is generated.
+//
+// It's not clear why the destructors are deleted prematurely. It might be a
+// compiler optimization in new compiler versions.
+//
+// The solution here is to call the `unregisterAllCreators` function from the
+// plugins translation unit in the hopes that it will force the compiler to keep
+// the destructors.
