How can I control ASAN not to catch c++ function __cxa_throw

When I run my code with libasan.so, it will stuck in the lib. And the version is 9.5.0.There is a part of backtrace.

I do not get the resolution, but I throught if i can avoid asan catch c++ throw. I learn it can set

export ASAN_OPTIONS=intercept_cxx_exceptions=false

in run time When I asked chaptapt.But it doesn`t work. And there is not this keyword in asan source code when i searthing.
