Chun-min, Alex, not sure what's up here. Something weird with the way we're using the unique_ptr ? Stacks are a bit weird, but I'm sure we can guess what's up.

Is there any memory-checking tool for OS X 10.12 to help us to debug?

Valgrind won't work. You need to do an ASAN build [0]. Ping me on irc if you need help for this.

No reports in last one month[0] in FF55. I guess it might be fixed by bug 1358896(pull 288).
