I thought that there was a problem with aggregate_value_p when, after reading that comment, I attempted to set DECL_RESULT to 0 in a toy front end that I am working and the result was a segmentation fault inside aggregate_value_p. Thank you very much for showing that the problem was in the comment. Rafael
