One of the things that would really help us is if you could split 
up the one file that is miscompiled into a number of files each 
of which has exactly one function, and try to figure out which 
function is miscompiled. One of the reasons why we have trouble 
doing anything with your report except for poking in the dark is 
because it is very hard to figure out what exactly goes wrong in 
applications that we don't know, and we usually need quite some help 
from application developers to figure out where the bug is. So if 
you could try to cut the problem down to one or a few functions, it 
would be a tremendous help. The next step is to determine for which 
arguments this function does the wrong thing, and to put together 
a small testcase where this one function is called with just these 
parameters for which the output is known. 
 
Thanks
