jprobe bug?

[Martin Hunt]

I just noticed this afternoon that my poll probe example wasn't working
correctly.  I can simplify it to a single empty probe and still see the
problem.  The probe is

void fastcall inst_add_wait_queue (wait_queue_head_t *q, wait_queue_t
*wait)
{
  jprobe_return();
}

I'll attach full source.

I compile that code into a module and load it.  Then launch Firefox.
Firefox almost never launches.  It usually hangs immediately.  In the
rare case it launches, if I close it and try to launch it again, it
hangs. Eventually the system locks up.

This happens on an x86_64 running 2.6.10-1.753_FC3.smp and an x86
running 2.6.10-1.741_FC3.smp
