T2 multithreaded test is failing with 30 threads with 8/23 build. Let me know if you want to take a look and need some time on cluster.

[Pavani Puppala (pavani-puppala)]

This failure is due to using C++ library functions that are not thread safe functions like strtok(), there are other functions that are not thread safe which need to be checked. Assigning to Daniel since he working on removing all non thread safe standard library function calls from T2 driver code.

[RuoYu Zuo (ruo-yu-zuo)]

This should be already fixed since Daniel's changes for function safety were checked in. I have run the multi-thread tests, with 10 threads, 20 threads, 32 threads and 50 threads, this core no longer occurred. Change the status to "Fix Committed".
