I fail to see why, at least on SPARC, %o7 should be good enough.
You set a breakpoint at the return address assuming that you
will reach it when you finish the function. On Sparc, if you
set it at the address in %o7, you will be setting the breakpoint
at the call instruction address, not the address where the
function will return. Either you never hit that breakpoint,
or you hit it on a different iteration.
In any case, for Sparc, on entry to a function the CIE doesn't
even say that %o7 is the return address.
