c++ - Derived class vtable corrupted? -

-

need in root causing vtable corruption issue(not sure if that’s happening). here simplified version of code.

class cbase { public:     cbase()     virtual ~cbase()     virtual void base_virtual_fn1() = 0;     virtual void base_virtual_fn2(); private:     cdata   _data; };  class cderived : public cbase { public:     cderived();     virtual ~cderived()     virtual void base_virtual_fn1();     virtual void base_virtual_fn2();     virtual void derived_virtual_fn1();     virtual void derived_virtual_fn2(); private:     // contains vectors , maps, integers, bools.  };

when create instance of cderived , call derived class virtual function derived_virtual_fn2 other function gets called i.e. derived_virtual_fn1.

calls base_virtual_fnx has no issues.

this happens object created on heap , not local object.

these classes in shared library. i’m using gcc 3.4.2 on linux (sles 10). there no pragma pack directive in of code , there mix of c , c++ code (extern c used). issue here?

i forgot mention there there tons of other code (executable, libraries)

here nasty mistake made took me forever find. compiler/debugger/valgrind gave me no insight going on. there should someway debug these kinds of errors:

the base class compiled in library "some_package" defined:

class interface {     virtual int function1(int); #ifdef some_package     virtual int function2(int); #endif     virtual int function3(int); }  class base : public interface {     int function1(int);     int function2(int);     int function3(int); }

the derived class compiled later without some_package defined

class derived : public base {     int function1(int);     int function3(int); }

calls function3 caused jumps function2 able figure out debugger, took me long time find cause.

cocoa - Nesting arrays into NSDictionary object (Objective-C) -

-
i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.
