Hi,
I am using asan to detect our app's memory problems, but when run our app
with asan,
the SEGV happened, the backtrace is like the following
-----------------------------------------------------
(gdb) bt

Any ideas about it? is it the problem of our app or problem of asan?
how can I know them？ thanks in advance
