            [BZ #14277]
            * intl/dcigettext.c (_nl_find_msg): Avoid use after potential
            free.  Simplify list management for _LIBC case.

Fails to check malloc's return in intl/dcigettext.c (_nl_find_msg):
~~~~
 		      freemem_size = INITIAL_BLOCK_SIZE;
 		      newmem = (transmem_block_t *) malloc (freemem_size);
 # ifdef _LIBC
		      /* Add the block to the list of blocks we have to free
			 at some point.  */
		      newmem->next = transmem_list;
		      transmem_list = newmem;
~~~
If malloc fails then newmem is NULL then newmem->next results in a fault.
The fix is easy enough, check for newmem != NULL, and fall through to
the error condition below which returns (char *) -1 e.g. resource error.

The problem is that returning (char *) -1  will break all sorts of other
callers, so while what we did is correct, the real failure case fix is slightly
broader.
