I don't think the question can be answered from the information you have 
given.  It could be that it is due to a change in your configuration after 
stage 1 or 2 was partly built, and that starting over cleanly could fix 
it.  In the case to which you refer, which you apparently didn't look it, 
it means the compiler you have generated is broken, but you haven't given 
any indication of the reasons.
