The increment is performed + on a global variable counting the number of allocated + stages. Because the memory allocation function can fail and + therefore internally call fatal() this construct is undefined + arcording to ANSI C. This means that it is not clearly defined + if the numstage counter is already increased when fatal() is + called or not. While older gcc versions increase the counter + after the memory allocation function has returned, on newer + gcc versions (3.x) the counter gets actually increased + before. In such a case the stage destructing process will try + to free an uninitialised and maybe attacker supplied + pointer. Which again could lead to remote code + execution.
