New issue 672 by leoxiang...@gmail.com: FileDescriptorTables double free
problem when use protobuf both in shared library and in main.cpp
https://code.google.com/p/protobuf/issues/detail?id=672
What steps will reproduce the problem?
1. compile *.pb.cpp file with main.cpp to generate executable
2. compile *.pb.cpp file witeh other.cpp to generate a shared library
test.so
3. dlopen test.so in main.cpp and call the function in shared library
4. when process end, there will be a double free corruption catched.
What is the expected output? What do you see instead?
hello in so
