New issue 675 by vxm...@gmail.com: memory leak
https://code.google.com/p/protobuf/issues/detail?id=675
A memory leak is detected by vld(visual leak detector).
I think the problem is caused by this function:
void InitEmptyString() {
empty_string_ = new string;
}
empty_string_ will not be deleted later.
In previous version protobuf-2.5.0, empty string is a global std::string
const ::std::string kEmptyString;
protobuf version: protobuf-2.6.0
OS: windows 8.1
build env: visual studio 2013
Some output generated by vld:
d:\sdk\protobuf\protobuf-2.6.0\src\google\protobuf\generated_message_util.cc
