New Revision: 55120

Modified:
   pypy/branch/smalltalk-shadow-changes/pypy/translator/backendopt/test/test_malloc.py
Log:
failing test about malloc removal in the presence of cast_pointers. The
problem is that malloc removal replaces each occurence of the same
structure in the input args of a block by the exploded vars, which means
that there is no global view of what the variables currently are.
