Possibly these were too trivial to expose any potential problems that you
may have been referring to, so would be helpful if you could write a more
concrete example / sample code.

The trick is to have a sufficiently complicated expression to force
the compiler to run out of registers.

You can use -ffixed-XXX to keep the testcase simple.
