You can call ShutdownProtobufLibrary() before program exiting and after
that there should be no such "leaks".

[protobuf] C++ - Protobuf descriptor static memory leaks

2017-11-09 Thread Arpit Baldeva 
Hi,

Currently, protobuf generated code makes allocations in the static 
descriptor objects. For example, valgrind reports

 
   Memcheck:Leak
   fun:malloc
   fun:_ZN20PassthroughAllocator5AllocEmPKcj
   fun:_Znwm
  
 
fun:_ZN6google8protobuf14DescriptorPoolC1EPNS0_18DescriptorDatabaseEPNS1_14ErrorCollectorE
   fun:_ZN6google8protobuf12_GLOBAL__N_1L17InitGeneratedPoolEv
   fun:_ZN6google8protobuf8internal16FunctionClosure03RunEv
   fun:_ZN6google8protobuf18GoogleOnceInitImplEPlPNS0_7ClosureE
   fun:_ZN6google8protobuf14GoogleOnceInitEPlPFvvE
   fun:_ZN6google8protobuf12_GLOBAL__N_121InitGeneratedPoolOnceEv
   fun:_ZN6google8protobuf14DescriptorPool24InternalAddGeneratedFileEPKvi
  
 
fun:_ZN5Blaze51protobuf_blaze_2fprotobuf_2fblazeextensions_2eproto12_GLOBAL__N_118AddDescriptorsImplEv
   fun:_ZN6google8protobuf8internal16FunctionClosure03RunEv
   fun:_ZN6google8protobuf18GoogleOnceInitImplEPlPNS0_7ClosureE
   fun:_ZN6google8protobuf14GoogleOnceInitEPlPFvvE
  
 
fun:_ZN5Blaze51protobuf_blaze_2fprotobuf_2fblazeextensions_2eproto14AddDescriptorsEv
  
 
fun:_ZN5Blaze51protobuf_blaze_2fprotobuf_2fblazeextensions_2eproto27StaticDescriptorInitializerC1Ev
   fun:_Z41__static_initialization_and_destruction_0ii
   fun:_GLOBAL__sub_I_blazeextensions.pb.cc

Is there a convenience function that could deallocate these objects so that 
I don't have to suppress these allocations? Found this relevant issue 
- https://codereview.appspot.com/7918 - 9 years ago. 

Thanks.
