annotate generator/abstractmetabuilder.cpp @ 393:1049b01aebd2
Fixed generator segfaults on OS X 10.6.
Regarding the change to dgenerator.cpp, I am not actually sure if 0 is the correct value to pass, but it seems to work and the code which had been there before was just plain incorrect ? it read past the list boundaries.
