First thing is that you did *not* attach anything. 

IMO the only bug is with what you expect gcc to do. As I answered you in a 
previous mail, gcc does not preserve all registers during function calls and 
gcc also does not *expect* all registers to be preserved during function calls.

I'd like to ask you kindly to carefully read the documentation before sending 
alarming messages to this list that might make other users ring alarm bells 
without reason.
