unzip.cpp는 오래된 안정적인 볼 unzip.h, 아직 나는 다음과 LLVM SA 논리 오류 얻을 :이 unzOpenInternal의 구조체 할당 혼동되는 것처럼

것 같습니다를 전화하기 바로 전에. unzFile에 대한 후속 캐스트가 다른 함수에서 얼마나 많이 영향을 미치는지 확신 할 수 없습니다.
코드가 정확하므로 clang 그룹 및/또는 Apple에 버그 보고서를 제출할 수 있습니다.

@ "아날로그 파일": Thx, 나는 버그 보고서를 제출할 때까지 똑같은 생각을하고있었습니다. 나는이 질문에 "요리하다"시간을 줄 것이다. : ^) – mda
