<pre>When encountering a possible malloc(0), the clang analyzer reports a "Undefined
allocation of 0 bytes (CERT MEM04-C; CWE-131)" bug. This text is wrong, since
malloc(0) is not *undefined*; rather, it is *implementation-defined*.
A global s/Undefined allocation/Implementation-defined allocation/ in the
clang-analyzer source code should fix this.</pre>
