The source code is as follows: template <int T1> struct dt { template <int T> dt<T> operator +(const dt<T> input) { } }; dt<3> func1(dt<3> input) { return input; } int dut() { dt<3> const_zero; dt<3> lll = (func1(func1(const_zero))) + func1(const_zero); dt<3> kkk = (func1(func1(const_zero))) + func1(const_zero); return 1; } I have debugged this code and find that this bug maybe is caused by wrong node generation in AST tree. One node called CPPASTAmbiguousBinaryVsCastExpression is incorrectly added to AST.
Putting the code above into the CDT editor does not trigger an error. How do you trigger the error? What kind of exception is thrown (a stack trace could help)? What version of CDT are you using?

What version of CDT are you using? I only use the CDT core part, org.eclipse.cdt.core_5.3.0.201106081058.jar and attach the source file, org.eclipse.cdt.core.source_5.3.0.201106081058.jar, to eclipse for debugging. Here is my parse code: 'filename' is the path of the source code. FileContent codeReader = FileContent.createForExternalFileLocation(filename); ScannerInfo scannerInfo = new ScannerInfo(); IScannerExtensionConfiguration configuration = GPPScannerExtensionConfiguration.getInstance(); IScanner scanner = new CPreprocessor(codeReader, scannerInfo, ParserLanguage.CPP, NULL_LOG, configuration,IncludeFileContentProvider.getSavedFilesProvider()); ICPPParserExtensionConfiguration config = new GPPParserExtensionConfiguration(); ISourceCodeParser parser = new GNUCPPSourceParser(scanner, ParserMode.COMPLETE_PARSE, NULL_LOG, config); IASTTranslationUnit tu = parser2.parse();//This line will throw exception. I debug into it step by step. The stack trace will be: Exception in thread "main" java.lang.NoClassDefFoundError: com/ibm/icu/text/MessageFormat at

It's CDT8 on linux.
Apperently you are using the parser in a non-standard way and you do not provide the class 'com/ibm/icu/text/MessageFormat' Nevertheless the code snippet is interesting, because the 'RecursionResolvingBinding' should not be created.
Added testcase and fix. You should still make sure that your JVM can load the class 'com/ibm/icu/text/MessageFormat'.

What do you mean a non-standard way? Could you detail it? Thanks.

(In reply to comment #5) > What do you mean a non-standard way? Could you detail it? Thanks. Normally you use CDT within an eclipse application, which will take care of loading the necessary bundles. Since you do not do that, you have to provide the necessary jars yourself.
