The FAQ does explain (in section 12.2) what does error=4 and error=6 mean. 
It cannot explain about *all* the possible error values because then I'd need
to put all of the monumental Intel manual inside the FAQ ;-).  If you need to
interpret every bit in the crash message, download the Pentium manuals from
the Intel's site.

For Page Fault, the value 7 is like 6: it means you tried to write to an
invalid address.  The LSB (the one which distinguishes between 6 and 7) means
that the fault was caused by a page-level protection violation.  Since all
DPMI servers I know about don't implement page-level protection, I wonder how
did you get that.  Did you compile your program with YAMD, perhaps?

I don't see anything interesting.
