Thanks Luis for the feedback, I think you've narrowed down the problem.
That happens on targets that do 'on the fly' checking of available
watchpoints (like ppc64 does). It's not a matter of number of available
hw watchpoints as my original message suggests.

'continue' doesn't work either. From what I understood, 'break' or
'continue' will terminate the iteration of the innermost nested loop,
that seems to be the gdb_test_multiple block. That's why it continues to
the second gdb_test_multiple block and wrongly increments hwatch_count
instead of going to the beginning of while block.
