That means that there are likely 63k submittals of one form or another wherein there may be a large number of duplications. Of course not all bugs are equal in the eyes of their creator. The "defects" could range from "Correct the spelling of XYZ in a comment in module ABC" all the way up to "If I click on this icon the disk drive is erased and the whole system locks up." Still in all, I think a reasonable presumption about a large system written in a weakly typed language would be that some significant portion of the known defects would never occur if it had been programmed in a more rigorous language such as Ada. In the past, I have collected enough data on similar project comparisons to be able to convince myself and others that Ada resulted in a decrease of defects by a factor of four over similar systems with weak checking.
