Comment (by [EMAIL PROTECTED]):
Interesting.
If you can make this happen at will, a few things to try come to mind:
a) To see if there is something magically wrong about that first write, do
a "write for nothing" at the beginning of the program . I.e. put a "movb
al,(%edi)"
right after "movl $_iseg, %edi".
b) To see if it's somehow timing related, add a delay loop just before the
copy starts.
c) Instead of single-stepping, put a breakpoint before the code, then let
it run full speed after it hits the breakpoint.
