+        *
+        * Since ExportJobData is a C-style struct dynamically allocated with
+        * MEM_mallocN (see above), its construtor is never called, therefore the
+        * ExportSettings constructor is not called which implies that the
+        * SimpleLogger one is not called either. SimpleLogger in turn does not call
+        * the constructor of its data members which ultimately means that its
+        * std::ostringstream member has a NULL pointer. To be able to properly use
+        * the stream's operator<<, the pointer needs to be set, therefore we have
+        * to properly construct everything. And this is done using the placement
+        * new operator as here below. It seems hackish, but I'm too lazy to
+        * do bigger refactor and maybe there is a better way which does not involve
+        * hardcore refactoring. */
