Hi, I have a piece of code like this : #ifndef __TEST_HPP #define __TEST_HPP #define TEST_NAMESPACE_BEGIN namespace test_namespace { #define TEST_NAMESPACE_END } TEST_NAMESPACE_BEGIN class SampelClass { public: } TEST_NAMESPACE_END #endif //__TEST_HPP When I format it, I got following exceptions. If I use namespace directly without define a macro, format works fine. The exception call stack is: org.eclipse.cdt.internal.formatter.AbortFormatting: [9/1] Unexpected token type, expecting:12, actual:Token type=65 image =class offset=181 at

This MIGHT have been fixed together with #402006 (website: https://bugs.eclipse.org/bugs/show_bug.cgi?id=402006 ) Thanks to Sergey Prigogin
This bug should be closed, no more reproducible in CDT 9.7
Closing as WORKSFORME per comment 2.
