I've got the following problem with TSAN (g++ 9.4.0) on Ubuntu 20.04.2 - it doesn't symbolize symbols from dynamically loaded SOs (while does for the executed binary itself):

I found the same problem in my search https://groups.google.com/g/thread-sanitizer/c/OsLLKNGxNUA, but unfortunately this person doesn't have a good solution. I want to get the stack information in TSAN warning. Hava a good day:D
We need to import dynamic libraries that are not displayed in advance. Please refer to the following instructions：
export LD_PRELOAD=$LD_PRELOAD:/lib/x86_64-linux-gnu/libtsan.so.0:/integration/lib/libplanner_runner.so:/integration/lib/libplanner_common.so
notice:
If dynamic libraries need to be imported after program startup, the above instructions will cause errors. There is currently no solution for such dynamic libraries, such as the libplanner_component.so in my question here.
if you have some good solutions for it, please tell me, have a good day, everyone:D
