The problem is IPA split is splitting the function mem_alloc correctly, though
it should have removed the malloc attribute on the split function.
This was introduced by:
2012-01-11  Eric Botcazou  <ebotcazou@adacore.com>

...
        * ipa-split.c (split_function): Skip the return value for the split
        part if it doesn't return.

Though it was always there really.
