	Have you verified that the probes are actually firing when enabled on  
x86?

	It may be that you are just getting lucky that things link on x86,  
but they
aren't actually working.

	I would try with the Solaris toolchain and see if things work  
correctly. If
they still do not, you've likely got a real bug.
