Using Cygwin on Windows XP __and__ setting "structural parsing" (note the the auto discovery stuff is on to get the right include path), the below file, also in attachment put the parser in infinite loop in ExpressionParser.errorHandling(), the swith case never return. #include <iostream> #include <string.h> #include <vector> using namespace std; int main() { vector<char> A(10); cout << "Tamaño = " << A.size() << endl; for(size_t i = 0; i<A.size(); ++i) A[i]= i + 'a'; cout << "Contenido " << endl; for(size_t i = 0; i<A.size(); ++i) cout << A[i]; cout << endl; A.push_back('z'); cout << "Nuevo Tamaño = " << A.size() << endl; cout << "Nuevo Contenido " << endl; for(size_t i = 0; i<A.size(); ++i) cout << A[i]; cout << endl; return 0; }

wrong component should be CDT_parse
Are you seeing this w/HEAD or 2_0 branch?
I cannot reproduce this with either HEAD or 2_0. Can either of you try this again and let me know if it's still reproducible? Thanks in advance
I can not test it since all I got now is an ArrayIndexOOBException See log below. Let me update again from the repository and I'll get back to you.

Andrew has committed a fix to the ArrayOutOfBoundsException. He apologizes to all who suffered.
> He apologizes to all who suffered. 8-) It is better, meaning that the ArrayIndexOOB and the forever loop are gone. You can turn this to "Fixed" as I can now open the file in the ceditor. The verification was done using the head. Thanks. But now I have a new problem .. better use a new PR.
Lowering to Major since I cannot reproduce the problem.
Sorry, I didn't see your comment. Marking as fixed. Thanks Alain!
Still happens, but not the IndexOOB but the loop Chris will attach a test case and the debug stack

I'll still getting this problem when opening "cygwin/usr/include/inttypes.h".

Something pretty bad has happened here in the scanner ... IToken '{''s next token is itself, thus, errorHandling loops forever.
#error was encountered in ieefp.h and caused Scanner2 to get confused.
Fix applied to HEAD & 2_0. #error was causing an infinite loop.
