Attached is a patch that implements your suggestion. Tested on ppc-aix
using AdaCore's GDB testsuite.

While at it, the powermac XCOFF backend also seemed to be using
the same code that eventually leads to the dangling pointer, and so
I fixed it as well. It's untested, but seems straightforward enough.

OK to commit?
