One of you seems to have thoroughly spoiled his mail address,
so this goes over the list:

Can you try to boil down the problem from xx MB sources to at most, 
say, 1000 lines of code? I have the feeling that there is either a 
problem with an uninitialized variable in libm (unlikely), or W95
plays around with the status word of the numeric processor. I haven't 
ever seen the error 183 msg, so I guess it is a W95 message. 

Or, ZIP the whole stuff and send it uuencoded to me (do _NOT_ 
reply to the list ;-), it once happened (?) to me on another list),
if there are no copyright problems.
