crash

问题 I have a small program, written in C++ that contains a class with a large array. The class looks like this: class Test { public: Test(); ... private: int myarray[45000000]; }; Now, this array is read in from a file. I would like to do this with the constructor directly, instead of bothering to call any extra functions. The array only needs to be read in once, and afterwards will not change anymore. It has the exact size specified. My constructor looks like this: Test() { memset(myarray, 0,

问题 I'm using the latest stable releases of Mono/Monotouch/MonoDevelop on a iOS 5.0 iPhone and iPad. I have a UIWebView that in the emulator never crashes however randomly on the actual devices it crashes on EXC_BAD_ACCESS.

问题 Let's say that a function which returns a fixed ‘random text’ string is written like char *Function1() { return “Some text”; } then the program could crash if it accidentally tried to alter the value doing Function1()[1]=’a’; What are the square brackets after the function call attempting to do that would make the program crash? If you're familiar with this, any explanation would be greatly appreciated! 回答1: The string you're returning in the function is usually stored in a read-only part of

问题 I have an application that runs just fine in the debug build, but when I start it in the release build, I get a unhandled Exception at 0x0043b134 in myapp.exe: 0xC0000005: Access violation while reading at position 0x004bd96c If I click on 'break' it tells me that there are no symbols loaded and the source code can't be displayed.
