The program created objective c++ is getting crash

I am developing a application to get list of installed software in Mac OS X 10.5 or above. The program is created using objective-c++ (c,c++, obj-c). Every time开发者_如何学JAVA I run the program, it is crashing.

int main (int argc, const char * argv[])  
{
     NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];    
     //My part of coding
     [pool drain];  // This is the crash prone place
     return 0; 
}

Here I'm providing project setting details:

file extention: .mm

compiled as : objective c++

Objc GC : unsupported

libraries used : libxml2.2.dylib, Foundation Framework

target platfom: x86_x64

development: Mac OS X 10.6.8, Xcode 3.2.6

Application type: console application

I don't know any other option need to set to compile objective c++. Any help regarding this would be appreciated.

yes. I already set base sdk as 10.5

Here is the log trace:

I have one more question. Is it valid to release the obj-c object in c++ class destructor? like this

myclass::myclasss() { myobjcinterface* myobjc = [[myobjcinterface alloc] init]; }

myclass::~myclass() { [myobjc release]; }

Yes.

As for your EXC_BAD_ACCESS, if it's hapening on drain of an autorelease pool, it's almost certain that you have autoreleased something and released it, so the pool is trying to release a dangling pointer.

Try setting the environment variable NSZombieEnabled to YES and then running your program. It should give you diagnostics about over-releases.
