I have the log file attached.
What code is on this line?
This is not always the same line when the problem appears.

It can happen, that I press F8, when the grey bar is on the line with
the Writeln statement and the debugger does not come back to the next
line with the Sleep statement.
I made another simple test case, which fails on Windows 7 (but works on
Windows 2000):
program project2;
begin
Writeln('Test');
Writeln('Test');
Writeln('Test');
Writeln('Test');
Writeln('Test');
Writeln('Test');
Writeln('Test');
Writeln('Test');
Writeln('Test');
Writeln('Test');
Writeln('Test');
Writeln('Test');
end.
On Windows 7, I am not able to step until the end of the program. At
some time, when I step over with F8, the grey selection bar does not
come back to the next Writeln statement. I can see, that the target has
stopped, because there is no further output in the console.
[valuable information snipped]
You could try, if you are on that line, instead of stepping (F8), set a
breakpoint the next line (lines, if there is a conditional), and use F9.
Then, with F9 you should be able to use the pause button
And then try, what happens if you hit the pause button in the IDE?
yes, pause seems to work.
So the remote printed connection lost, when you pressed stop in the IDE.
Then it was still connected?
The exact message from the target is:
Remote side has terminated connection. GDBServer will reopen connection.
Listening on port

Though, I am not sure it is communication, it might be timing on the local interaction between gdb and the debuggee. It is well possible that the connection with the win2000 also affects speed, and that gdbserver may hit a race condition. (gdb has one on win32 where it fails to step, because it interrupts the target, before the target fully resumed / well something roughly like that).

Under windows 64 bits, the program does not recognize the glut32.dll properly and returns a message. Note: I would suggest you to use FreeGLUT if you want to keep the API. It's a drop in replacement for the original GLUT, but also provides 64-Bit libraries.
