Application hangs in __sanitizer::internal_sched_yield()

[getsoubl]

Hello,
We are running an application using sanitizer . Seems that the application hangs in #0 0x00007ffff6f0ea4b in #0__sanitizer::internal_sched_yield() () from /lib64/libasan.so.5
#1 0x00007ffff6e55015 in pthread_create () from /lib64/libasan.so.5

Is any known bug?
Is any hint what goes wrong and this behaviour is appeared?
The g++ version is g++ (GCC) 8.2.1 20180905 (Red Hat 8.2.1-3)
Thank you
George

Any hint ?

It might be helpful to see the callstacks of all threads (thread apply all bt in gdb)

I checked the thread apply all bt. As I mentioned in my previous comment , seems that the main thread that creates working threads, hangs internal_sched_yield. I consider that it never returns.
