There are 4 threads are created:
(trusty)zhaoqin@localhost:~/Workspace$ ls /proc/14276/task/
14276 14309 14313 14315
(trusty)zhaoqin@localhost:~/Workspace$ ls DynamoRIO/builds/build_x64_dbg.git/logs/hello.14276.00000000/
hello.0.14276.html log.0.14276.html log.1.14309.html log.2.14313.html log.3.14315.html
However, GDB shows only one thread. The error message of "unreadable memory at 0x18" suggest it is more likely it is accessing the TLS segment. So DR may not handle the Go program TLS correctly.
