This is the test I was referring to in
http://gcc.gnu.org/ml/gcc-patches/2011-05/msg02184.html

The test, taken from the C testsuite, creates hundreds of thousands of
shared bindings.  Without sharing support, the streamer was trying to
instantiate new objects, and ICEing eventually when the stack was
blown.

I have several other C test cases that are currently causing problem
(or used to be a problem).  I'll keep adding some representative tests
as I fix them.


Diego.
