Using the default configuration?

Here's the GDB output when I do it:

A program never returns. If you just want the GDB prompt back, you
could set a breakpoint at cyg_test_exit before starting the test.

Or you can break execution. When I press C-c after the above output, I
get:

Program received signal SIGINT, Interrupt.

I don't see the problem you reported when running the clock0
test. Notice that the problematic address is in ROM space. The PowerPC
simulator can only run tests configured for the minimal simulator, and
these are normally loaded at address 0x4000. 

Perhaps you ran a test configured for the Cogent board by mistake?

Thanks,
