Please considered this...
http://gcc.gnu.org/ml/gcc-patches/2011-01/msg01206.html

It must be **transaction_safe** not transaction_pure.

Moreover I think we should also add ECF_MALLOC (malloc attribute) because
otherwise the allocated memory will not be considered as local.

Extract from trans-mem.c: thread_private_new_memory()
  if (stmt && is_gimple_call (stmt) && gimple_call_flags (stmt) & ECF_MALLOC)
    /* Thread-local or transaction-local.  */
    ;
  else
    retval = mem_non_local;

Thanks.
