New issue 479 by [email protected]: Deallocating an proto class(with a
string) in C++ gives a heap error when "delete stringvariable" is called
http://code.google.com/p/protobuf/issues/detail?id=479
What steps will reproduce the problem?
1.I have proto file that generates a class with some classes and string in
it .
2.I instantiate an object of that class put in some fields and then use
serialize it:
{ int sizeArr = request->ByteSize();
char* aux = (char*)malloc(sizeArr);
request->SerializeToArray((void*)aux,sizeArr);
}
3.After this i declare another object in a scope so that the destructor
could be called,and parsed the serialized array of the first class in which
i set some values :
{MsgWebRequest webReqTest;
webReqTest.ParseFromArray(aux,sizeArr);
}
What is the expected output? What do you see instead?
The expected output should be that the second object should deallocate
successfully, but it doesn't, it gives me a corrupt heap , and breaks at
dbgheap.c(in the call stack the last class that is called from the
protobuffer is delete variable(where variable is a string type, that i
seted before)).
What version of the product are you using? On what operating system?
Windows vista 64, protocol buffers 2.4.1
