It's hitting the breakpoint:
Process 1 stopped
* thread #1: tid = 0x0001, 0x00004130 factorial`main(argc=1, argv=0x0000b100) +
28 at factorial.c:32, stop reason = breakpoint 1.1
frame #0: 0x00004130 factorial`main(argc=1, argv=0x0000b100) + 28 at
factorial.c:32
29 }
30 */
31
-> 32 base = 10;
33
34 printf("Factorial of %d is %d\n", base, factorial(base));
35 return 0;
But I don't get the prompt. If I do debugger.SetAsync(False), it hits the
breakpoint and gives me the prompt, but I don't get the source list that I
expect when I hit a breakpoint.
The process is launched - it's running on a simulator that I'm talking to using
gdb-remote.

Your debugger is in synchronous mode which means process.Continue() won't
return until your process stops. If you just want to run your target and not
wait for it to stop try:
debugger.SetAsync(False)
then do your process.Continue()
This should let your script exit and then catch the event back in the debugger
when it does stop. Then CTRL+C should work as well.
NOTE: process.Continue() won't work unless your process is already launched.
Just wanted to make sure you weren't expecting it to launch your process.
