It seems we should test it with ASAN regularly.

I found that the diff code has a problem. Will fix it soon.

Other problems seem to be not in uftrace. The C++ full demangle code is in libstdc++ and script is from the python runtime. Maybe we should suppress ASAN for external codes if it's possible.
