Symify source (like the source of all other DJGPP utilities) is in the 
v2/djlsr200.zip archive.  You will find symify.c in src/debug/common 
directory.  I think it can be easily changed to read from the secondary 
screen, given a certain switch on the command line.

No, in gcc, the optimizations shouldn't do that.  It can be that the 
traceback you get is from the DPMI host and not your program.  Maybe 
posting an example of such trace could help in finding an explanation to 
this.
