Previously, the manual pages and the output of "strace --help" contained inconsistencies. This update corrects these errors. Now, the descriptions for the listed options on the manual pages and in the output of of ‘strace --help’ contain the same information. (BZ#533199)

Previously, the CLONE_PTRACE flag was set in the arguments of a clone when it was called with the flag CLONE_UNTRACED. Due to this behavior, strace traced the child process for clones called with the flag CLONE_UNTRACED.This update does no no longer trace children with CLONE_UNTRACED. Now, the tracing of child processes behaves as expected. (BZ#642389)

Previously, the decoding of 64-bit arguments of certain system calls was incorrect. This update corrects this issue. Now, 64-bit arguments of system calls are decoded as expected. (BZ#654515)

Previously, waitpid waited for children created by clone even when the options "__WCLONE" or "__WALL" were not present. Due to this behavior, the process became suspended. This update does no longer suspend the process in the waitpid system call. (BZ#661748)
