C++ application built with librdkafka with GCC TSAN crashes when starting

[thilinak]

Discussed in #4927

^{Originally posted by thilinak December 9, 2024}
My application is built with librdkafka 1.6.0. It runs okay normally but when the application is built with TSAN flags (GCC) the application fails to start and crash stack is shown as below. Please help to resolve this.
