 Description   

ThreadSanitizer, similar to AddressSanitizer, allocates a large volume of shadow (virtual) memory to track the addresses for memory reads and writes. When using the gcore command this memory ends up in the core dump. Until the changes in SERVER-69255 can be made we should not attempt to capture core dumps on TSan build variants using gdb.
