You should probably be using "run" or "start" instead of "continue".
The commands you quote don't work at all for me. Specifically I do:

$ arm-none-eabi-gdb a.out
GNU gdb 6.3.50.20051102-cvs
...
(gdb) target sim
Connected to the simulator.
(gdb) load
Loading section .init, size 0x18 vma 0x8000
...
Transfer rate: 358912 bits in <1 sec.
(gdb) start
Breakpoint 1 at 0x81d4
Starting program: /home/paul/arm/foo/a.out
0x000081d4 in main ()

My guess is you aren't resetting the simulator between runs, you're just 
jumping back to the start of the program.  This is unlikely to work because 
the previous run will have closed the stdio file descriptors.
