An updated strace package that fixes one bug is now available for Red Hat Enterprise Linux 6.
The strace program intercepts and records the system calls called and received by a running process. It can print a record of each system call, its arguments and its return value. The strace utility is useful for diagnosing, debugging and instructional purposes.
The strace utility did not properly track switches between 32-bit and 64-bit process execution domains (so called "personalities") when tracing multiple processes with multiple "personalities". This caused strace to output the wrong system call names and arguments for the traced processes. This update corrects personality tracking in strace so that it now prints system call names and arguments as expected.
All users of strace are advised to upgrade to this updated package, which fixes this bug.
