+Subject: [PATCH] fix segmentation fault in precompiled header generation
+
+Prevent a segmentation fault which occurs when using incorrect
+structure trying to access name of some named operators, such as
+CPP_NOT, CPP_AND etc. "token->val.node.spelling" cannot be used in
+those cases, as is may not be initialized at all.
