Hi, Michael, Looks like this particular problem might be caused by an incorrect handling of a special case in the function ibis::selectClause::addAgregado. The variable generated from selectParser.yy:252 (selectParser.cc:252 actually refers to selectParse.yy:252) was passed to the function addAgregado, however, the expression count(*) (generated to replace avg(something) with sum(something) / count(*)) must have appeared in the select clause already and therefore is no longer needed. The fix is to free the pointer to the variable object in the function addAgregado.
Please give SVN Revision 582 a try when you get the chance and let us know if it continues to have problems. Thanks.
