strace-4.12-6.el7

The strace utility intercepts and records the system calls that are made and received by a running process and prints a record of each system call, its arguments, and its return value to standard error output or a file. It is often used for problem diagnoses, debugging, and for instructional purposes.

Fixed bug(s):
* Previously, programs which set the CLONE_PTRACE flag on new threads caused undefined behavior of the strace tool, because it uses the ptrace() function for its operation. As a consequence, such programs could be neither traced nor executed properly. The strace tool has been modified to ignore threads with an unexpected CLONE_PTRACE flag. As a result, programs which use CLONE_PTRACE execute properly under strace.
