The attached patches fix, and have been
tested with `make check-c++` on linux-x86_64. The trunk patch applies
and tests cleanly on gcc-4_7-branch. The gcc-4_6-branch patch is
significantly simpler, as Paolo suggested on the bug.

The test is still inadequate, but given that there's no way to force
get_temporary_buffer to return a short buffer, I'm not sure how to
improve it. It might be possible to use set_memory_limits(), but that
would require a very complex test program to make sure exactly the
right operator new call fails.
