MySQL Connector/C++ BAD ACCESS crash

由 不问归期 提交于 2019-12-01 07:10:39
Using C++ in Xcode I try to access a MySQL database with the MySQL Connector/C++. Problem is that the program (compiled with Xcode) always crashes with EXC_BAD_ACCESS (code=13, address=0x0) when calling driver->connect(url, user, pass) In Xcode I created a complete new project (OS X > Command Line Tool), inserted the code (see below) in the main.cpp, added Boost and MySQL Connector header include paths as well as libmysqlcppconn.6.1.1.1.dylib as Link Library and hit the Run button. Next thing is, when I compile the program manually using c++ -o test -I /usr/local/mysqlConnector/include/

EXC_BAD_ACCESS on device, but fine on Simulator

由 强颜欢笑 提交于 2019-12-01 06:12:12
问题 I have a scroll view app which runs fine on the simulator, however, when installed on the device, it gives me an EXC_BAD_ACCESS, when i attempt to scroll one page. I have ran it through Instruments with Allocations and Leaks, but nothing is leaked and no zombies are messaged... i'm just curious what could cause such a difference in simulator vs device? Any ways to debug this, since my symbolicated crash log (partial below), doesn't seem to be very symbolicated. Exception Type: EXC_BAD_ACCESS

EXC_BAD_ACCESS on NSManagedObjectContext save method inside NSOperation and ARC, why?

由 强颜欢笑 提交于 2019-11-30 23:43:08
问题 I have found some problems when saving NSManagedObjectContext inside NSOperation with turned on ARC. Without ARC everything was fine before. It is always gives EXC_BAD_ACCESS during saving. The code looks like this: //on the main thread -(void)someFunc { array = ... //fetching an array of entities from a core data for(SomeEntity * obj in array) { NSSomeOperation * op = [[NSSomeOperation alloc] initWithValue:[obj someField]]; //start an operation } } //NSSomeOperation implementation //... -

EXC_BAD_ACCESS on objc_setAssociatedObject with -weak_library /usr/lib/libSystem.B.dylib linker flags

由 倾然丶 夕夏残阳落幕 提交于 2019-11-30 19:53:14
I have a EXC_BAD_ACCESS when I call objc_setAssociatedObject with the linker flags : -weak_library /usr/lib/libSystem.B.dylib linker flags. I absolutely need the linker flag because of this , do somebody know a workaround? (I also have a crash on dispatch_async but I can work around that... Also, I'm building a iOS 4 only feature on my app that is iOS 3 compatible) EDIT: With more research, I found this and this question but no more answer... The problem is simply a bug in the iOS Simulator. The codes works fine on the device. I've filled a radar on Apple's bug reporter (radar://9470793) EDIT:

I'm trying to replace my current viewController with a new one. I've been able to do this before but I'm having some issues with BAD_ACCESS. This is the code that will run when I want to replace the current view with a new one.
