当在我的应用程序内部按下主页按钮，然后重新进入应用程序时，我经常会在重复几次之后遇到崩溃（应用程序通常会自动重启）。日志提示我在malloc_error_break中设置一个断点来调试我已经完成的过程，问题似乎是在baseapi.h（一个用于调用tesseract的API）的函数中捕获的：
int Init(const char* datapath, const char* language) {
return Init(datapath, language, OEM_DEFAULT, NULL, 0, NULL, NULL, false);
}
我在读完这里的一些帖子之后理解这与尝试dealloc或释放一些未分配的对象有关。但我不确定从哪里开始。问题是否比我上面显示的功能更进一步？
编辑堆栈跟踪：
