When I use valgrind on my programs that use protocol buffers, I get many
"possibly lost" warnings from valgrind. They all appear to be caused by
descriptor pools. I've looked at the code briefly, and I don't really
understand why these warnings happen, but I haven't tried too hard to
figure them out.
Is there any hack I could apply in order to suppress these warnings,
either in my code or in my copy of the protobuf library? Thanks,
Evan
