[antlr-interest] Assertion failure in cicularqueue.hpp

[togol machillan]

Hi,

I get the following output due to failure of the assertion in the removeItems (size_t) method defined in the mentioned file. 

p ----> start of paragraph ...
 col == 1
Assertion failed: nb <= entries(), file u:\antlr-2.7.5\lib\cpp\antlr\circularqueue.hpp, line 59

The rule which generates this error looks like this:
paragraph{ 
	   std::cout << "p ----> start of paragraph ..." << std::endl;
	 } 
	 : pkeyword = p_keyword_nolist {col == 1}? ...  

The starting portion of the input file is given below. The assertion fails when the parser tries to process the TITLE line, although "TITLE" is defined as a literal in the p_keyword_nolist rule and starts in column 1. Can somebody explain what I need to do to avoid this situation.

Input file:

DYNAMICS
    DYNAMICS RESULTS=ON

TITLE 'IsoCyanate Leverkusen' 
...

Regards,

Togol
